After two and a half years running Disney, during which time the Mouse House released hits like Pirates of the Caribbean 4, Alice in Wonderland, Toy Story 3, The Muppets, and The Help -- but also a string of disappointments topped by last month's quarter-billion dollar bomb John Carter -- studio head Rich Ross is out. "The best people need to be in the right jobs, in roles they are passionate about, doing work that leverages the full range of their abilities," Ross said in a statement. "It's one of the leadership lessons I've learned during my career, and it's something I've been giving a great deal of thought to as I look at the challenges and opportunities ahead... I no longer believe the Chairman role is the right professional fit for me." [Deadline]
