Although a third 'Hangover' film hasn't yet been greenlit, the fact that 'The Hangover, Part II,' set a new box-office record for R-rated comedies with Friday's $30 million opening makes a third installment look like a sure thing.

Director Todd Phillips and the series' stars are eager for a third go-round with the Wolf Pack, and one star would love to see the action move to Amsterdam.

At last week's Las Vegas premiere, Jamie Chung (who plays Stu's fiancée) had her pick: "Probably Amsterdam. If you think of the coolest, craziest cities in the world, it would have to be Las Vegas, Bangkok and Amsterdam."

Justin Bartha (Doug) agrees: "Amsterdam could be a different kind of hangover. It could be fun. And Zach [Galifanakis] will probably already be there."
