Who knew that a simple cameo could take over an entire movie? Now that Mel Gibson is out, go-to guy Liam Neeson is in for a brief appearance in Hangover 2. Gibson's cameo as a tattooist was cut and then given to Neeson amid rumors that star Zach Galifianakis was the catalyst behind getting rid of the troubled actor.

Neeson tells Variety that he's thrilled to be part of the movie, which co-stars his A-Team pal Bradley Cooper. "I just got a call to do a one day shoot on Hangover 2 as a tattooist in Thailand, and that's all I know about it," he says. "I just laughed my leg off when I saw The Hangover. I was shooting in Berlin earlier this year and rented it on the hotel TV."
