Other movies that end with pensive stares...

I really liked the final shot, with Tommy's look telling everything that was going on inside his head (which, of course, is open to interpretation). Got me thinking, what are other movies that end with the main character(s) providing us with a long deep look or expression that ties the whole movie together -without explanation- and has you, the viewer, going 'wow, that look says it all.'

The ones I know are; Michael Clayton, The Graduate, and Oldboy.

I'm curious to know what others come up...
