If I Can Only Move

There are times when the most important thing a hero can do is the slightest move.

For instance, the hero is immobilized and is facing certain doom if he remains that way. Suddenly, everything depends on moving just enough to reach and activate something vital like his giant robot remote control or Transformation Trinket to summon help or activate his power mode to break free before it's too late. Unfortunately, the thing needed is often seemingly out of reach.

With the maximum of suspenseful music and editing, the hero, often saying "If I can only move.." gives it everything he's got and just barely makes it. With that help is summoned or the transformation has begun and he's back in action.

A variant is when a patient in a hospital has a severe back injury and there is a real danger of paralysis. In that case, the medical staff and patient tensely hope against hope for any movement to indicate the limbs are still functioning.

Professional Wrestling has a specific subtrope: Ricky Morton

Anime and Manga

 * In One Piece, near the end of the "Enies Lobby" arc, Luffy is exhausted and trapped in the ruins of a tower with several battleships poised to blow him away. Problem is, his fight with Rob Lucci took all his usual Determinator tendencies to bring down, leaving him so weak he really can't move at all, even with a few scenes of numerous allies cheering him on. Fortunately, Robin's ability allows her to move him herself from a distance.
 * In Yu Yu Hakusho, Asato Kido doesn't allow his paralysis to stop him from telling Yusuke who the evil doctor is by writing the name with his own blood.

Comic Books

 * One of the most famous Spider-Man comic book images is Spidey pinned beneath tons of rubble. The rare isotope that his dying Aunt May needs is mere feet away, and the room is being filled with water. He keeps trying to lift the rubble enough to escape, but it's VERY heavy. Cue the final Herculean effort!
 * Like many of his famous comic book scenes, this is given a Shout-Out in The Spectacular Spider-Man, only Spidey is trapped under a ceiling fixture and it's Gwen Stacey who's in trouble.
 * In the Marvel Universe, Dr. Don Blake has been tied up at least once and has to struggle to reach his walking stick to strike it and transform into Thor.
 * '"If I can just reach my utility belt..."
 * The ending of Bone:

Film

 * Kill Bill: "Wiggle your big toe."
 * Maybe not 100% true to this trope but the Bride does this after coming out of a coma and trying to solve the problem of atrophy. Her arms however had been getting plenty of exercise, apparently.
 * What Lies Beneath, the scene with Michelle Pfeiffer slowly drowning in the bath tub, trying to pull the plug out with her toe.
 * Predator 2. Lieutenant Harrigan is on a ledge on the side of a building with the Predator hanging onto him. The Predator has activated his Self-Destruct Mechanism, which will destroy a large area and kill thousands of people. The Predator's cutting disk is embedded in the wall just out of Harrigan's reach.
 * Star Wars Episode V: The Empire Strikes Back has a variation: Luke Skywalker is trapped in the wampa's cave, dangling by one foot, and about to be turned into a meal by the monster. His lightsaber is just out of reach, but he's able to call upon the ability of The Force to call it to his hand and cut his way to relative safety at the last moment.

Literature

 * Not that it would've changed much but still in the end of Nineteen Eighty-Four the main "hero" is completely immobilised during his ultimate torment so that he couldn't turn away from the approaching cage with rats that he is afraid of and abhors to extreme.

Video Games

 * At the end of the Infocom game Spellbreaker, the Big Bad paralyzes you and then starts a Just Between You and Me speech that goes on just long enough to let you make one move at the last econd to stop him. Unfortunately, by that point your options are limited.
 * The player in the final battle of Another World - insofar as it can be considered a 'battle'.
 * Final Fantasy IV: During the fight with the Dark Elf, the party is struck down due to how their metal equipment is magnetically pinned down. Cue Cecil lamenting, "If I could only lift my sword!"
 * Final Fantasy VII: At one point Tifa is attached to a chair and has to wriggle (Fan Service suspected) enough to reach the key on the floor with her feet and use it to free herself before the room fills with gas.
 * Call of Duty 4 Modern Warfare has some minor instances of this, notably at the end . But this plays an even bigger role in Call of Duty Modern Warfare 2, particularly   or even more pivotally

Western Animation

 * Frankenstein, Jr.: Played straight in "The Menace from the Wax Museum" where Buzz Conroy is immobilized with wax and everything depends on moving his ring to an open candle flame to contact his robot.
 * Frequently invoked in old Space Ghost cartoons: "I... can't reach... my... power bands!"
 * Popeye always seemed to get stuck with his spinach just out of reach.
 * The Superfriends often find themselves in this situation with the need to activate their powers and they are both just out of reach. However, Gleek often solves the problem since his body can act as a conduit for their powers.
