I watch a movie a long time ago it has a Women lock in a closet or a basement of a big house (Mansion) she either escapes or tries to get away not to later on shes at a muesem were these guys are going to steal a big huge painting.the have a huge truck to load it in. A chase insues inside the muesum. It's a color film probably made around the 50's and i'm almost sure it's a musical but I could be wrong.

I've notice from the musical thread that you Guys & Gals know a lot about musicals and classics and this movie has been going around in my head for a long time any suggestion would be cool thanks.
