Zach Galifianakis On Mel Gibson's 'Hangover 2' Cameo: I Don't Hire Or Fire Anyone

Apparently, Zach Galifianakis would rather talk about Debbie Gibson than Mel Gibson.

When Galifianakis stopped by "Today" this morning to promote his upcoming film "Due Date" (out November 5), he was asked for his thoughts on the controversy surrounding his other Todd Phillips-directed comedy "The Hangover 2." Specifically, what the heck happened with the whole Mel Gibson cameo?

"I do not consult on the movies that I'm in," he said. "I just show up and I say my lines, usually terribly, and I do consult on dialogue. But as far as hiring and firing of actors, I have no insight into that world whatsoever."

He does have insight into '80s pop idol Debbie Gibson and her bathroom, however. "If you have any questions about Debbie Gibson, I can answer that," Galifianakis joked. "Debbie Gibson, if I remember correctly, lives in this neighborhood and has a very nice toilet."

A couple weeks back Gibson (Mel, that is), who had been set to cameo as a wacky Bangkok tattoo artist in "The Hangover 2," was suddenly dropped from the film and quickly replaced by Liam Neeson. In a statement, director Todd Phillips said that he "thought Mel would have been great in the movie" but that he "ultimately did not have the full support of my entire cast and crew."

Speculation swirled that Galifianakis was among those left less than thrilled with Gibson's casting after he said in a radio interview that he was "in deep protest" with a movie he was working on. That movie was presumed to be "The Hangover 2" and the reason for his discontent was inferred to be the casting of current Hollywood pariah Gibson, though this has never been confirmed.

While Galifianakis is keeping mum on the Gibson flap, Phillips has been vocal in his support for Mel. Last week he said: "No one was ever fired. It's a term that is so obscene to me... Someone was doing me a favor to come in for a two-minute cameo, and we changed it. It wasn't like we fired somebody. [Gibson] was just doing a favor from the beginning."

Do you think Galifianakis had anything to do with Gibson's removal from "The Hangover 2"? And would you have liked to see Mel in the movie? Tell us in the comments!
