Liam Neeson Brings 'Gravity' To 'Hangover 2,' Director Says

Plus: 'Hangover' breakout star Ken Jeong is 'just happy' he's involved in the sequel.

With all the talk surrounding "Hangover 2" — specifically Mel Gibson's heavily hyped cameo being scrapped/ switched to Liam Neeson due to alleged disgruntled reactions from Zach Galifianakis and the rest of the cast — what we're really missing are details about the plot.

Here's what we know so far: The film is being shot in L.A. and Thailand, with the boys (Bradley Cooper, Galifianakis, Ed Helms, Justin Bartha) headed to the Far East on some sort of all-dude excursion.

When we caught up with director Todd Phillips and breakout star Ken Jeong at the premiere of "Due Date," we asked them for a few sequel teases. What takes the boys to Thailand?

"A plane," Phillips answered cheekily, indicating he wouldn't be divulging any secrets at all.

And how did Phillips choose Neeson for the cameo? "There's a lot of people [we considered]," he said. "He has gravity. Liam brings a sense of gravity. But, you know, it's a cameo, and we don't like to talk about it, because it's [supposed to be] a surprise and now it's ... I don't like to justify it."

As for Jeong, we tried our best to find out what his zany character might be up to as well.

"No comment!" he exclaimed. "I'm just happy that I'm in it. For me, this is not predestined to happen so I'm just so happy I'm involved in any moment. Anything Todd asked me to do, I would do. Anything."

What do you think of all the "Hangover 2" talk? Will it be as good as the first film? Share your thoughts in the comments!
