Zach Galifianakis: Shooting 'The Hangover 2' In Bangkok Is 'Un-Boring' (VIDEO)
Entertainment Tonight visited the Bangkok set of "The Hangover, Part II" to check in on the boys and see how they were holding up in Thailand. The film is a follow-up to the 2009 mega-hit, which became the most On Demand movie ever.
"Bangkok sort of tops Las Vegas in a huge way," Bradley Cooper told ET.
Zach Galifianakis added: "I don't really want to go back because I find that I might be bored when I go back to the United States. This is, like, the most un-boring place. I just love it."
The quartet filmed scenes all around the city and enjoyed the town's river ferries to get around.
As for special guest stars, director Todd Phillips revealed that Mike Tyson makes a cameo in the film's sequel.
