My Best Friend's Girl (1983)

Sinopsis

The charming Pascal, owner of a clothing store in Courchevel, and the chubby and scruffy Micky, disc jockey in a nearby club, are best of friends. Pascal accumulates women, much to the chagrin of Micky, who is consoled of his failures by listening to his friend talk about his successes. Viviane arises, ravishing and icy, but she's seasonal. Pascal, sincerely in love, seduces her and then leaves. This is a dire situation for Micky: Pascal is far away and the beauty is so kind to him. Complications arise once Pascal returns.
