Oz Great and Powerful

How and when did director Sam Rami become mainstream? Anyway, ne'er do well Oscar, AKA Oz, the stage magician, wishes to be someone important. Well, getting accidentally transported to a magical land might give you more than you wish, as Oz has to save the kingdom from an evil witch. Disappointingly, the acting is horrible, direction poor, and F/X lame, plus it's too long.
