What is the movie I am thinking of?

I was watching a movie in film class, and I wasn't paying attention. I need to know the plot of this movie for a test next class, which is this Tuesday, so that gives me enough time to go to the movie store and rent it. Thing is, I forget what it's called, which would make it rather difficult to find.

Here is what I remember from it, good luck.

It was black and white

Main character was a man

Some people in it tried to steal a famous statue/sculpture, but the one they ended up stealing turned out to be fake

It's a rather famous movie

I link to the movie on http://www.imdb.com/ would help me identify whether it's the correct movie or not, thank you.
