For quite some time, the only thing we've known about the planned 3-D treatment of "Arabian Nights" is that it will star Liam Hemsworth. Now we know who he'll (potentially) be facing off against: Anthony Hopkins, as the evil sorcerer Pharotu. The veteran actor is in final negotiations to take the role, THR reports. Hopkins will also be appearing with another Hemsworth, Liam's brother Chris, in next year's summer Marvel adaptation "Thor." You can check out the full story over on THR's Heat Vision Blog.
