Liam Neeson has replaced Mel Gibson in 'Hangover 2' just 24 hours after Gibson was removed from a cameo role as a tatoo artists in the new movie.

Neeson got the call after fellow actors refused to work with Gibson and flew to Bangkok on Thursday.

"I just got the call to do a one-day shoot on 'Hangover 2' as a tattooist in Thailand, and that's all I know about it," Neeson told Variety Magazine.

"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."

Director Todd Phillips put out a statement after Gibson was cut:

"I thought Mel would have been great in the movie and I had the full backing of 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," he said.

Actor Zach Galifianakis is said to be the reason why Gibson was removed.

Interviewed on the Comedy Death-Ray podcast last week, Galifianakis said, "A movie you're acting in, you don't have a lot of control -- you just show up and vomit your lines out. I'm not the boss. I'm in a deep protest right now with a movie I'm working on, up in arms about something. But I can't get the guys to [listen] ... I'm not making any leeway."

"It has something to do with a movie I'm working on, yeah. I'll tell you about it later. It's very frustrating."
