Who am I this time?

From a short story by Kurt Vonnegut. Christopher Walken 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 screen. Susan Sarandon is new in town, a lonely itenerant telephone company employee. On a whim, she auditions for and gets the part of Stella to Walken's Stanley when the theater group does A Streetcar Named Desire. Before anyone realizes the problem, she falls deeply in love with the sexy brute, not knowing what the real man is like.
