The Venture Bros./Trivia

"Doc Hammer: "That was Batman. Batman's readin' crap that we wrote."
 * Hey, It's That Voice!: Dana Snyder, the voice of The Alchemist, is also the voice of Master Shake on Aqua Teen Hunger Force which he also created.
 * The creators mentioned (when on a panel for a Dragon Con) that they asked Snyder to sound more like Master Shake when voicing the Alchemist than he had originally done.
 * They also intentionally invoked this trope with Kevin Conroy in season four, complete with Actor Allusion.

Jackson Publick: "Yeah... don't be afraid to sound more like Batman!""


 * General Treister is voiced by Toby Huss, who also voiced Kahn and Cotton Hill in King of the Hill. Cotton and Treister sound almost exactly alike, and both being crackpot southern military men, it makes sense.
 * Stephen Colbert as Prof. Impossible. At first, anyways.
 * Orpheus' Master sounds suspiciously like Jon Benjamin, aka Benjamin Katz or Coach McGuirk.
 * That's because he's voiced by Sterling Archer.
 * Brock is Joe Swanson from Family Guy, aka Patrick Warburton. He's also Kronk, making the role Hilarious in Hindsight, because he was the big sidekick guy to a skinny, inept mad scientist there, too.
 * Fans of Teenage Mutant Ninja Turtles 2003 can recognize Dean Venture's voice as Michael Sinterniklaas, who plays Leonardo. Newcomers to the series will probably say "Hey, it's Nnoitra from Bleach!"
 * "Self Medication," guest-starring John Hodgman, Seth Green, Patton Oswalt, and Brendon Small, is basically "Hey, It's That Voice!: The Episode."
 * Nathan Fillion as Brown Widow.
 * Retroactively subverted in "Ghosts of the Sargasso". One of the pirates is a spit for Seasick Steve, baseball cap included, but he barely talks, if at all (and of course the voice actor wouldn't be Seasick Steve).
 * James Urbaniak shows up in the Fallout: New Vegas DLC "Old World Blues" as 0, and pretty much every line he speaks is a glorious, unapologetic Actor Allusion to Dr. Rusty Venture, to the point where he even says certain phrases Rusty's said in the show, the exact same way he said them, in the exact same voice. He's even the robotics expert in the group of Mad Scientists, he's grumpy, untrusting, and employs a lot of Buffy-Speak. He also totally broke a bunch of robots on purpose.
 * One of Us: In the commentary for "The Diving Bell vs. the Butterglider", Doc Hammer and Jackson Publick mention several trope names before specifically stating that they read TV Tropes.
 * Shrug of God: After an episode was made that strongly implied if not stated outright who the boys' mother was, the creators said that they're still not sure themselves whether or not she is, as they don't plan too far ahead with episodes and it just sort of happened.
 * Talking to Himself: Every comedy duo in the show except for the Venture boys themselves (Monarch and Dr. Girlfriend, 21 and 24, the Murderous Moppets, Billy and White, Watch and Ward, Doe and Cardholder) are voiced by writers Doc Hammer and Jackson Publick; Publick also voices Hank, Sergeant Hatred, Action Man, Col. Gentleman, Ned, the Pirate, and Dr. Henry Killinger. He talks to himself a lot as a result. Doc Hammer does it the most often between Dr. Girlfriend and 21, while James Urbaniak gets in on the act with all Dr. Venture/Jonas, Jr. conversations. The season four episode "The Revenge Society" has Urbaniak in a three-way conversation with himself, but the writers try to keep the number of Talking to Himself instances down. For example, any time 21 and 24 interact with the Venture twins, 21 always pairs up with Hank so that Jackson Publick doesn't play both sides of the conversation; similarly, most of these characters are often kept inside their Cast Herds so that they do not interact with the voices most similar to their own (the Action Man has yet to talk to Sgt. Hatred, for instance, while 21 and Billy are always kept far away from each other).
 * What Could Have Been: Listening to the creator commentary on some episodes is kind of sad once you hear how many interesting tidbits had to be cut for time:
 * The Freudian dream sequence in "The Doctor is Sin" had a fairly interesting backstory that had to be cut.
 * "Doctor Quymn, Medicine Woman" was slated to have a flashback implying that Dr. Quymn could be the boys' biological mother (hence why she resembles Dean so much) as well as some Pet the Dog moments for Dr. Venture.
 * A deleted scene on the season four vol disc would have shown Dr Killinger showing up to help  recapture some of that sweet, sweet evilness.
