That didn't take long. Just days after signing on for a cameo appearance as an "outlandish character"--possibly an expat tattoo artist--in The Hangover 2, the angry, angry Aussie has been fired from the Bangkok-set bromance following complaints from the cast and crew. Star Zach Galifianakis was rumored to be the driving force behind the campaign to ax Gibson, something director Todd Phillips neither confirmed nor denied in his prepared statement announcing the decision. Said Phillips:

"I thought Mel would have been great in the movie and I had the full backing of [Warner Brothers president] Jeff Robinov and his team. But I realize filmmaking is a collaborative effort, and this decision ultimately did not have the full support of my entire cast and crew."
In conclusion, Mel Gibson is now alone and unemployed in Bangkok. More on this story as it develops.
