Good Luck Chuck

As a boy, Charlie (Dane Cook) was cursed with something that has since become a "gift" for some: after sleeping with a woman, she always finds her true love in the next man and marries him. That's how Charlie, known as "Lucky Chuck," is sought after by countless single women. But when Charlie finds the perfect woman (Jessica Alba), he faces a "small problem": he can't sleep with her... because if he does, she will find another man and lose him forever.
