In somewhat surprising news, Disney Chairman Rich Ross has rather abruptly resigned from the company, THR is reporting. “I believe in this extraordinary Walt Disney Studios team, and I believe in our strong slate of films and our ability to make and market them better than anyone else,” Ross, who only had the position since late 2009, said in his resignation letter. “But, I no longer believe the Chairman role is the right professional fit for me.” It is unknown why he is leaving the company so suddenly, but Pixar honcho John Lasseter may or may not be behind it, as he is reportedly not a fan of Ross. It also might be because of the box office results for John Carter, which, as you possibly may have heard, cost Disney a lot of money to make. In any case, Ross’ resignation is effective immediately.
