One of my favorite caper movies is called The Silent Partner, which has also been released under the title Think of a Number. It stars Elliot Gould and Christopher Plummer. Plummer is a bank robber, and Gould gets wind of his intention to rob the bank he's working at. And when the robbery goes down, Plummer gets away, but Gould snatches the loot...and understandably, this makes Plummer very, very angry...and that's only the first twenty minutes of the movie.
There's a Michael Caine movie called The Silver Bears that I remember enjoying an awful lot, too. And Burt Reynolds as an aging safecracker in the movie Breaking In really worked for me.
