7. Nicolas Cage
Oh boy, where do I start? For anyone who is too young to remember, Nicolas Cage is an Oscar winner; he was without doubt box office royalty in the 90's. It's hard to digest the fact that a guy can go from starring in Leaving Las Vegas, The Rock and Raising Arizona to what he is now. As Nic Cage's real life persona has become more erratic, so has his choice of films; following his last big hit with Face/Off, Cage's filmography is full of failure after embarrassing failure, with an occasional bright spot only to be followed up by further failure. For example, he went from a good and relatively mooted appearance in Kick Ass to yet more drivel in Season of the Witch and Trespass. The most baffling thing is that the erratic behaviour has bled into his performances; picking bad roles is one thing, but there is simply no excuse for bad acting from a man who has won an Academy Award.
