Ed Helms has described the script for The Hangover: Part II as insane.
The actor reprises the role of Stu this week two years after the success of the first movie.
Speaking to Access Hollywood the actor said: "When I read [the script] I was like, 'This is insane'.
"If we're going to make a sequel, we have to make it worthwhile, so it's gotta be crazy, it's gotta be insane!"
"I've never had any dignity and so why start now? It's kind of out there, [but] it's not mean spirited."
However the actor admits that the biggest challenge that he faced during the shoot in Bangkok was coming down with food poisoning.
"If you've ever had really bad food poisoning, then you know about a tenth of what I endured. I thought my body was going to explode."
The Hangover - Part II is released 26th May.
