Movie Title? Robbing Banks, 2003-2006: Ending - he hid himself in a partition in bank

I forgot what's the title of this movie. The ending of the movie is: he hid himself in a partition at the wall of the bank, and wait till 1 or 2 days after the incident and he came out.

Of course, he robbed the banks. He got a couple of accompliance, but all of them are masked. There were hostages inside before police broke into the banks. And all the hostages(including those robbers) wore masked and the same clothes as well.

Any1 can help? It's a movie from 2003-2006, i cant rmb which year

Inside Man maybe...

ah thanks man!

Can I just thank you, ichiclay, for your thread title. Seeing a whole page of titles saying 'forgot his movie' or 'help please' does my head in.
