The Face with Two Left Feet (1979)

"What happened to him shouldn't happen to a dog."

Gianni, a hotel cook, is frustratingly in love with the sexy blonde DJ at the nightclub "John's Fever" but he can't dance. When one of the cook's coworkers draws a mustache and beard on a poster of John Travolta everyone somehow finally notices that Gianni looks exactly like Travolta and the game is on.
