10. JOHN CENA IN THE MARINE (2006)
Oh, this movie was bad. In 2006, WWE thought it would be a great idea to turn their most musclebound superstar into a movie star. The Marine turned out to be less enjoyable than taking an hour-and-a-half bike ride without a seat. The script was horrid, Robert Patrick looked like he was in a REM cycle while acting, and the director, John Bonito, was apparently drunk during his college film classes.
But no travesty can compare to John Cena's painful attempt at acting. He's already about three lug nuts and a circuit board away from being a robot as it is, but, apparently, when people actually try to make him show emotion, he becomes even more soulless.
