Who Am I This Time? (1982)

Harry is a shy hardware store employee. But whenever he takes a part in a local amateur theater production, he becomes the part completely--while on stage. Helene is new in town, a lonely itinerant telephone company employee. On a whim, she auditions for and gets the part of Stella to Harry's Stanley when the theater group performs A Streetcar Named Desire. Before anyone realizes the growing affection between Helene and Stanley, she falls deeply in love with the sexy brute, not knowing what the real man is like.
