Simple Jack is a character played by Tugg Speedman (Ben Stiller) in the movie-within-a-movie for Tropic Thunder, “Simple Jack”. Tugg Speedman faced harsh critical reception for Simple Jack, it being called one of the worst movies ever made. It tarnishes his reputation, causing him to fall into a crisis. Horse brush optional.
You may not have caught it, but in Tropic Thunder, Tom Cruise cameos as studio exec Les Grossman. He’s brash, foul-mouthed, hot-headed, and has dirty dance moves. He also has the hairiest, meatiest forearms you’ll ever see.
