Disney Studio Chief Rich Ross Out

The man who gave us High School Musical and Hannah Montana at Disney Channel has stepped down as the head of Walt Disney Co.’s movie studio after failing to find a winning formula for film. Named to the position in 2009, Rich Ross announced his decision to resign in an email to staff on Friday. A successor was not immediately named. Ross’s departure follows the monumental fiasco that was Disney’s John Carter, a sci-fi flop approved by Ross that will likely lose the studio about $200 million. Ross got his first job at the Disney Channel in 1996, and became president of the channel in 2004.
