(Cover) - EN Showbiz - Ed Helms has revealed that he found filming The Hangover sequel in South East Asia brutal.

The actor, who visited Thailand to film the sequel of successful comedy, explained that he found the country beautiful and majestic, but to work there was very different from his previous experiences.

While The Hangover was based around a group of men celebrating a bachelor party in Las Vegas, The Hangover 2 sees them travelling to Thailand for their friends wedding.

As in the first part, the men wake up after a drunken night out to find themselves in a post-blackout misadventure.

Thailand was brutal. It is a beautiful, majestic place to visit. But to work there, its just totally disconcerting and incredibly taxing, Ed told Total Film.

The actor explained that their groups excessive male energy didnt fit in particularly well with the Thai culture.

Ed admitted that he and his co-stars Bradley Cooper and Zach Galifianakis went through a mixture of emotions while shooting the movie.

To be thrust into that with this core group of guys with a lot of very aggressive male energy, it was intense, and, at times, scary. A lot of emotional highs and lows, he said. I think we all came back shell-shocked.

The Hangover 2 will be released worldwide from May 25. (C) Cover Media
