I saw a movie with Patrick Dempsy that involved a bank being robbed by two different groups of people at the same time.  Can't remember what it's called.

Brilliant, perfect!  And just like that flick, you often have a character who's more than they appear, so you can have that unsurprising last minute surprise.

And of course, everyone agrees to split the money, but at the end, only one person gets it.  And if it's a good and decent person involved in the heist, they won't keep the money but pay it to people who need it.

Tower Heist had the same thing, with a car made out of gold.  The people the bad guy screwed over got pieces of it in the mail.

I'm trying to remember what happened in Femme Fatale.  I remember Rebecca Romijn screwed over her gang and disappeared, and the second half was her gang getting out of prison and hunting her down.  I guess it's sort of a post-heist flick.  Though it wasn't very good.  But it does have the cliche that if a woman is the main character, she's highly se xualized.
