Disney CEO Bob Iger let the frog out of the bag at the company’s annual meeting in Kansas City today. “Somewhere in my mind I know that work is being done on a sequel,” he said, before stopping himself saying he didn’t know how much has been disclosed about a second ‘The Muppets‘ movie. Iger added, in response to a question, that design work is “just beginning” for the Avatar attraction planned for Animal Kingdom in Orlando — and “in all likelihood” it won’t open until 2015. He says the company is “working on some concepts” to introduce attractions involving Marvel characters. They’re also “kicking around ideas” to enhance the presence of Pirates Of The Caribbean and Cars at the parks. “It would be tough to do walk-around characters” for Cars, he said.
