Tom Mullen (Mel Gibson)

Ransom

Mel Gibson loses his cool thanks to a little egging on by Gary Sinise. If Ransom had been released 10 years later, there would be just as many "Give me back my son!" remixes as "This is Sparta!" on YouTube.

James T. Kirk (William Shatner)

Star Trek II: The Wrath of Khan

This Shatner classic needs no explanation, though after all these years we still aren't sure why the hell they added that ridiculous echo.

Vincent Hanna (Al Pacino)

Heat

Al Pacino is one of the greatest overactors of our time. We can't help but laugh whenever he breaks into one of his trademark rants. In fact, Pacino could have an entire list dedicated to him (stay tuned). We particularly like this one where he scares the piss out of poor Hank Azaria.
