Tread Softly (1952)

Odd mix of light, frivolous musical and dark murder mystery. Bentley's new musical needs a theatre so he arranges to hire old lady Nicholson's disused hall. Trouble is, they find a body behind the stage. The cast aren't phased by this and carry on rehearsing their silly songs and dances while the gruff cops investigate. After another murder, things get serious, but not much. A decidedly second-rate movie with a second-league cast of no distinction., only the backstage setting is of interest.
