No Time to Explain

"Wendy: Stop doing that! The Middleman: What? Wendy: "Don't talk until the world is un-doomed! You can't cry until you've reached the international safe house. You have forty seconds to save your friendship!" The Middleman: These rules exist for a reason. Wendy: Why? The Middleman: I don't have time to explain now."

- The Middleman, "The Accidental Occidental Conception"

This line is often used when the speaker in question has to take immediate action on something and can't explain it immediately.

The real reason it's used is to get the listener to change locations without explanation, as to effect an on-screen reveal. Or because the writer wants to keep a character's motivations secret from the reader (or hasn't thought them up yet) and can't have the character explain himself right now. Or because there'd be no conflict if a character actually bothered to exaplain something instead of leaving the other characters confused.

The phrase "I'll explain on the way there" can also be used, leading to a "Let Me Get This Straight..." moment in the new location where everything's summed up.

The only real justification is that it almost always takes longer to describe a given action than to just perform it - "It's easier to ask forgiveness than it is to get permission." Explaining the action may waste valuable time that should be spent performing the action - meaning there is no time to perform the action at all. Of course, there's always the possibility that the person asking forgiveness really should have gotten permission - Nice Job Breaking It, Hero.

Use of this trope can stretch credibility when the situation really can be summed up in only a few words. If you need somebody to run away, "No time to explain!" really saves you no time versus "There's a bomb!"

However, be careful: This is a favorite tactic of a High School Hustler in initiating a Bavarian Fire Drill. Not to be confused with the fun game of the same name.

Anime and Manga

 * Deliberately invoked in GaoGaiGar Final by Mamoru as he steals the Q-Parts.
 * In The Twelve Kingdoms, Youko Nakajima was an Ordinary High School Student until a mysterious blond man appeared in her classroom, swore allegiance to her, and urged her to escape as quickly as possible with not time for explanations. Shortly after, the school was attacked by monsters, giving some weight to his argument. Trapped in Another World Changeling Fantasy drama ensued, and it was a long time before Youko got an explanation.

Comic Books

 * Used by Reed Richards in every single issue of Fantastic Four ever..
 * To be fair to Reed Richards, most of the time he's dealing with shit so cosmically complex that "sufficient time to explain" would involve a several-hours long lecture series, and that's after his audience spent several years obtaining college degrees in various advanced sciences. Unless he's collaborating with a fellow supergenius like Victor von Doom or Tony Stark that day, he doesn't really have much choice in insisting that his audience just accept his premise and move on.
 * A particularly galling comic book example occured in a plotline in the X-Men books, especially Cable. Bishop, a time-travelling X-Man, was determined to kill an infant being protected by Cable because ... he never said, except that she threatened the future in some way. He constantly insisted that the X-Men would agree that she needed to die if only they knew what a horrible future her survival would lead to. But he just never had time to explain it to them. This made sense (or at least you could see how it made sense to him) when he was in a running gun battle with Cable. Made a little less sense when the X-Men caught him and held him onto him for a few hours before he escaped.

Films -- Live-Action
"-We've got to get to the shed! -What? Why do we need to go there? (a beat)"
 * The Princess Bride: "Let me explain. No, there is too much. Let me sum up."
 * Parodied in the fourth iteration of the Scary Movie series, when the Tom Cruise/|War Of The Worlds character says "We're leaving this house in 30 seconds, there's no time to explain", and a random passerby runs up to the window and screams "Alien Attack!". Tom admits that that pretty much covered it.
 * Also parodied in the Norwegian Dead Snow, when two of the protagonists are trying to keep the attacking nazi zombies from breaking into the house.

- Uh... no time to explain!

"Uncle Felix: (about the kids' parents being spies) There's so much I have to tell yu, but very little time to explain. Carmen: Uncle Felix! Uncle Felix: The first of which is (removes his fake mustache) I'm not you're uncle."
 * In A Nightmare on Elm Street, Nancy has a dream that she's seeing being killed in the jail cell he's in. She wakes up and gets Glen (Johnny Depp) to accompany her to the police station. They join up at Nancy's house and run to the police station. Nancy waits until they're entering the police station to tell Glen that she doesn't have any time to explain. What could they have been discussing the rest of the way there that was more important than the fact that  was being killed?
 * Spy Kids

Literature

 * Harry Potter: Ron gets increasingly more annoyed each time Hermione does this.
 * Of course, Ron also gets annoyed whenever Hermione attempts a detailed explanation so its not surprising Hermione eventually fell back on 'Shut up and just do it.'
 * This also happens in the Pendragon series, where Bobby, Gunny, and Spader initially think that stopping the Hindenburg explosion would save the future but upon a trip to the future Bobby and Gunny find out that
 * Painfully used in The Wheel of Time where there is no time to explain anything to Rand Al'Thor, on their long trek across the entire kingdom.
 * Moiraine had no intention of explaining anything. Aes Sedai seldom do. "Because I said so" is generally considered enough for most people.
 * With good reason, in this case. If Rand had turned out not to be the actual Dragon Reborn, it would be better if he hadn't been told the whole story. False Dragons (usually self-deluded into believing they're the real thing) often cause an incredible amount of havoc before they're brought down, so it's better not to give him any ideas until they can be sure he's The One.
 * In The Mysterious Benedict Society and the Perilous Journey, Reynie uses this to fend off questions from Joe "Cannonball" Shooter about why he and the other members of the Society aren't accompanied by any adults. It works quite easily, given that Cannonball is the sort of guy who is always on the move anyway.

Live-Action TV
"Junction Jack: We're going to Greg's house. Count Blah: What? Why? Jack: No time to explain! Count Blah: What are you talking about? It's a forty minute drive to his house, there's plenty of time to explain."
 * Used in Doctor Who :"Can't talk, must dash, explain later!" is basically one of the Doctor's catch-phrases. Any particular usage may be terrifyingly true or a typically clumsy bid to avoid the things he never, ever explains.
 * Deliberately over-used in Steven Moffat's Comic Relief parody "The Curse of Fatal Death", where it serves entirely as a Lampshade Hanging on things there simply aren't in-universe explanations for.
 * It was also used in the early days when the Doctor had more than one companion. For example, the Doctor and Susan would have one adventure, while something else happened to Ian and Barbara. The line was used so the Doctor didn't have to explain events to Ian and Barbara that the audience had already witnessed.
 * They didn't use the line, but in Highlander the Series, wouldn't have died if  had spit out one more sentence before dragging  to him.
 * The Twilight Zone episode "Passage on the Lady Anne" has a pretty Egregious example. At one point, the main characters are told "there's no time for lengthy explanations."
 * The Star Trek: Voyager two-parter "Future's End" starts one. A guy shows up in a time machine and immediately starts shooting at Voyager. This goes on long enough for the crew to figure out how to change their shields so his shots won't damage them anymore. The guy contacts them and says he has to destroy them for the greater good. When asked how their deaths would be for the greater good, he says "No time!" and goes back to shooting at them.
 * Used to good effect in Star Trek: The Next Generation episode "Hero Worship": The Enterprise is stuck in a Negative Space Wedgie which is shooting a World-Wrecking Wave at them. At the last second Data, in the throes of a Eureka Moment, orders the Deflector Shields to be deactivated—explaining, after the fact, that the World-Wrecking Wave was.
 * Parodied in Greg the Bunny:


 * 24 was quite fond of this trope. Just do what Jack Bauer says, people. He's always right, anyway.
 * A variation on Lost. Ben tells Sun and Jack that in thirty minutes, he can take them to a woman who can explain everything to them. Cut to them in the car, and Sun says "You said we'd be there in thirty minutes." He responds, "I didn't account for traffic."
 * Lost is rife with this in situations like "Come on, we need to get to the other side of the island, no time to explain" Cue several hour/day march across the island making you wonder if they simply marched in silence or maybe talked about the weather for ten hours and a camping stop, because they certainly must have had a few minutes to get caught up as they walked.

Videogames

 * Gorion's use of this trope is pretty much the entire reason Baldur's Gate happens. Which doesn't really make sense, seeing as all he ever had to say was
 * That's a summary, not an explanation. Consider the amount of follow-up questions. Then again, it also shows how it's not simply about having enough time to list the details but about having the chance to explain things in a way that doesn't cause a severe trauma (and/or to spit out something it's difficult for oneself to say).
 * In Fahrenheit (2005 video game),
 * Later on, when Lucas and Carla meet up and talk, even though there's plenty of time to explain, and Lucas actually gets a fair way into his explanation, he concludes that there simply isn't enough time to explain.
 * 'There's No Time To Explain!' is a Fahrenheit meme around these parts.
 * In Halo: Combat Evolved, Cortana sends Master Chief to warn Keyes not to activate Halo. She tells him she has no time to explain why, and this leads to a horrible mess. When they meet up, it turns out that it was Chief's fault. Women...
 * There is a flash game entitled "No Time to Explain" in which your player is intruded on in his home by him from the future, who informs the player of the fact and remarks "there's no time to explain!" before getting dragged out by a Giant Enemy Crab, leaving you to pick up a giant laser beam doubling as a jetpack to stop the crab. It turns out that
 * Said game is getting a proper multiplatform release out now, and a sequel too. And it's every bit as awesome as you could possibly hope it to be.
 * A doppelganger of yours says this literally in Simon the Sorcerer 2 after you break out of a cell. He also hands you a strange twig that teleports you outside and as it turns out, your doppelganger was.

Webcomics
"Vaarsuvius: ''You may have noticed that my explanations tend to take longer than the plans themselves."
 * Rephrased, with some self-awareness, in Order of the Stick:

"Vaarsuvius: ''Time is at a premium, precluding extended discussion."
 * Also:


 * Shows up in Keychain of Creation...after the heroes had already gone through an overly-long Transformation Sequence.

Western Animation
"Blue unicorn: Come with us to the future! Pink unicorn: We need your help to finish our snowman! Charlie: Snowman? What're you going on about? Blue unicorn: There's no time to explain! Pink unicorn: Grab on to our tongues!"
 * Parodied on The Simpsons, in the episode "Lemon of Troy": Nelson bursts into the classroom and shouts "Everybody come quick! Something's happened. No Time to Explain." Along the way, he stops take a drink at a fountain, and is asked if it wouldn't be simpler to explain the matter. His response is "No! I said there's no time to explain and I stick by that!"
 * Lampshaded in another episode, where Bart's fat-camp controller takes him home to see his family, and tells him "No talking on the way, it'll spoil the drama!"
 * Averted in an episode of Transformers Generation 1, where a human character does inform the main characters of a plot against them using one of their own as bait before action is taken. However, the leader only bothers to listen to a fraction of it, and only agrees to listen to the rest after he's mobilized his forces to save their friend.
 * Played straight in Transformers Victory - when Hellbat, Black Shadow, and Blue Bacchus are attacking a plasma energy facility on planet Micro, Greatshot orders them to let him take car of it, specifically saying that there's no time to explain.
 * "No time to explain, Fred!" was Super Chicken's Catch Phrase (well, one of them) in George of the Jungle.
 * A common phrase used in Jackie Chan Adventures is "Talk Later", used when a character has No Time to Explain and has to deal with a bigger problem.
 * Birdman plays this card in the Birdman episode "Avenger for Ransom", as he steals top-secret government documents and flies out the window, when just a few more words might have averted a skirmish with the military. Later, when he reveals that the documents he gave the villain were worthless, the general apologizes to him for doubting his word.
 * In the first season finale of Ben 10, Grandpa Max's response to Vilgax's attack on Ben is to take the RV and drive away in the direction of Mount Rushmore. Gwen asks why they're going there when Ben's in trouble. Max says there's no time to explain. Despite being on an extended drive, a la the above Greg the Bunny example. To the show's credit, Gwen chews him out for his oversecrecy in the next episode.
 * In Charlie the Unicorn 3:


 * In Sleeping Beauty the good fairies tell this to Prince Phillip as they break him out of Malificent's dungeon.
 * Angelina Ballerina: The Next Steps has the titular character saying this when her best friend, Alice, is saying about not liking of going to separate schools. Guess what she tried to her in the end.
