Charlie Logan (Dane Cook) is a relationship rabbit's foot: After sleeping with Chuck, women get hitched to the next guy they date. But when klutzy Cam (Jessica Alba) charms him, Logan's loath to work his love-her-and-leave-her magic. Good Luck Chuck aims for laughs with pratfalls and gross-out humor, but viewers looking for funny are out of luck.

The best of the lame Jessica-less extras is a sex-scene grid showing the ways Cook had to ''panto-bang'' during filming. D+
