The Big Bang Theory has been so popular, and so lucrative for its cast, they haven't ever really had to seek employment outside of this geeky small screen universe. But leading man Jim Parsons, who plays Dr. Sheldon Cooper, is about to make the rare leap to feature films. He has taken on the title role in Man-Witch. Don't worry, it's not about a dude mysteriously transformed into a Sloppy Joe. Though, that might sit okay with The Big Bang Theory's core fan base.

Man-Witch, deftly curbing from Warner Bros.' own Harry Potter franchise, tells the story of a schoolteacher, to be played by Jim Parsons, who discovers he has witch-like powers. He's taken in by a coven of real-life witches, and is quickly sent through 'witch school'. There, he is the only adult witch, surrounded by little girl 'witches-in-training'.

Jim Parsons will also produce Man-Witch, which has been kicking around Hollywood for awhile. The movie is now set up at Warner Bros. Jim Parsons is developing the project himself, and will work behind the camera alongside co-producer Neal Moritz.

Warner Bros. first picked up the project way back in 2005 as a pitch. They reportedly paid $750,000 against $1.5 million for it at the time. Todd Phillips had originally planned to direct, but a little movie called The Hangover got in the way. That comedy became a smash hit, requiring the director to return for two sequels. He eventually lost interest in Man-Witch.

The fantasy comedy had Jack Black set to star. He eventually dropped out and was replaced by Zach Galifianakis. The comedian later joined Todd Phillips for The Hangover, and the project was left to linger at the studio without any talent directly attached behind or in front of the camera.

Jim Parsons did make a rare appearance in the horror movie Visions, which is coming out later this year and stars Anson Mount, Isla Fisher, Gillian Jacobs and Eva Longoria. But he mostly uses his free time away from the set of The Big Bang Theory to participate in other endeavors outside of acting. He did voice the lead character in the animated comedy Home, which hit theaters last spring. He also appeared in the dramatic comedy Wish I Was Here, which was released in 2014. And he had a very memorable cameo in the 2011 Muppets movie. No other casting has been announced.
