The actor tweeted in August, "
I. Am. In. Oz. Sam refuses to tell me what character I will portray. Just know that the role is pivotal." Well I guess the role isn't pivotal at all, or it never was. There is a good shot that Bruce was just being sarcastic at the time, but either way he won't be making an appearance in the film and that's a shame. If you still want to get your Bruce Campbell fix you can watch him on the USA Network's popular cable TV series
Burn Notice, in which he plays Sam Axe.
Official Synopsis - Walt Disney Pictures' fantastical adventure "Oz The Great and Powerful," directed by Sam Raimi, imagines the origins of L. Frank Baum's beloved character, the Wizard of Oz. When Oscar Diggs (James Franco), a small-time circus magician with dubious ethics, is hurled away from dusty Kansas to the vibrant Land of Oz, he thinks he's hit the jackpot--fame and fortune are his for the taking--that is until he meets three witches, Theodora (Mila Kunis), Evanora (Rachel Weisz) and Glinda (Michelle Williams), who are not convinced he is the great wizard everyone's been expecting. Reluctantly drawn into the epic problems facing the Land of Oz and its inhabitants, Oscar must find out who is good and who is evil before it is too late. Putting his magical arts to use through illusion, ingenuity--and even a bit of wizardry--Oscar transforms himself not only into the great and powerful Wizard of Oz but into a better man as well.
The film will be released in theaters March 8, 2013.
