Boy, Did I Get a Wrong Number! (1966)

Other mistake: Not wanting his wife to see Didi, Tom locks Didi inside a tool shed. She pulls a cord to turn on an overhead light but the light that suddenly illuminates the interior of the shed comes from somewhere in front of her. Her shadow, which is the same height as she is, is cast on the wall behind her.

Lily: The whole thing sounds underhanded, disgraceful and messy, and you can count on me.
