What Happened?

Action films play well around the world, but many comedy hits in America aren't as big in foreign lands. What's funny, especially when based on dialogue and intonation, not to mention cultural norms, is tricky to translate.

So I'm surprised at how well What Happens In Vegas is doing overeas. It's a solid hit in America, inching toward $80 million, but non-domestic grosses should top $120 million. Is there something about Cameron Diaz that makes the split 40/60?
