Disney’s Oz The Great And Powerful is apparently on its way to a massive opening weekend, Deadline is reporting. The site is saying that tracking has Oz opening to $80 million or more, which would far and away give it the biggest opening weekend of 2013 so far. Even better are the film’s chances of being an international hit. The Wizard of Oz prequel–starring James Franco (Spider-Man) and Mila Kunis (the voice of Meg on Family Guy)–opens everywhere this Friday.
