The trio starred alongside Justin Bartha in the hit 2009 comedy, which saw them cause chaos in Sin City as a bachelor party went awry.
Director Todd Phillips is bringing the buddies back together for a follow-up and he has now revealed the sequel won't be returning to Nevada - they are shifting the action to the Far East.
He tells Empire Online, "It takes place in Bangkok and LA. There's gonna be some f**ked-up surprises. The three guys are back, Mr. Chow's back too."
And Phillips is promising fans a good quality follow-up: "I'm not delusional. I know what I'm up against. I saw Meet The Fockers. But we're aiming high. It's called The Hangover Part Two, you know."
