MUMBAI: Facing pressure over the box office flop of ?John Carter?, Disney Studios chairman Rich Ross has resigned.

Disney is expected to lose around $200 million from ?John Carter?. Ross was in the job for two and a half years.

Last year ?Mars Needs Moms? lost $70 million. Ross said in a memo that he no longer believed his role as chairman of Walt Disney Studios was the right professional fit.

Analysts have put some of the blame of the box office failures also on Disney CEO Robert Iger, who has been trying to modernise the studio.

Prior to this position, Ross had a lot of experience in television. But making the transition to film did not work. Reports also state that he did not surround himself with an experienced enough team.

MUMBAI: Disney has announced that its CEO Robert Iger?s contract would be extended though 31 March, 2015.

Then he will become chairman on the board. A replacement for Bob Iger has not yet been announced.

Iger succeeded Michael Eisner as Disney?s CEO in October 2005. There has been speculation that either CFO Jay Rasulo or Tom Staggs, who is the chairman of the parks division, could take over.
