One thing you did not mention in your post is if you were looking for 
"real-life museums" or if they could be fictional.  Depending on that 
disregard some of these answers.

If I remember correctly some of the "Pink Panther" movies are in a museum (I 
think that's where the diamond gets stolen from)

Isn't some of the Indiana Jones stuff in a museum?
Recent "The Mummy" and "The Mummy Returns"
"The Great Muppet Caper" features yet another diamond heist from a museum.
"How to Steal a Million"
"Head over Heels" its main character is an art restorer
