ET's own Kevin Frazier is exclusively on the set of 'The Hangover Part II' with Bradley Cooper, Zach Galifianakis, Ed Helms and Justin Bartha. Get an exclusive first look at the excitement of this summer's biggest comedy in ET's February Event!
"Bangkok sort of tops Vegas in a huge way," says Bradley, with a bit of a devious smirk, of the movie's new location.
All four stars of the original comedy blockbuster (which is the highest-grossing R-rated comedy of all time) are back, this time raising hell in exotic Thailand for Ed's character's wedding.
"The first one felt like a gritty, dirty -- the dark side of Vegas during the day," explains Bradley. "[This one's] a grand movie. This is the gritty, dirty reality of a city that's populated by, I think, 7 million people, so it's a lot different."
"I think people will be surprised at how gritty and crazy this movie's going to look," agrees Ed, adding, "There are no tigers – scripted – in this movie."
Zach is having such a good time, he might even stay in Thailand: "I don't really want to go back because I find that I might be bored when I go back to the United States," he says. "This is, like, the most un-boring place. I just love it."
Do the stars feel any pressure to top the first one?
"No," says Bradley. "It's more like the idea of just all of us being together again, playing the characters that we love."
Once again directed by Todd Phillips, 'The Hangover Part II' hits theaters May 26.
