The Walt Disney Studios has announced that its live-action release previously known as 1952 will be titled Tomorrowland. The film will be released domestically on December 19, 2014. George Clooney (The Descendants) is set to star.
Tomorrowland is written by Damon Lindelof and Brad Bird from a concept by Lindelof and Jeff Jensen. Lindelof (Star Trek, Lost, Prometheus) will produce and Bird (The Incredibles, Mission: Impossible – Ghost Protocol) will produce and direct.
Judging from that it will be something to do with a theme park and previous rumours have said aliens will also be involved.
Disney also have another film, Magic Kingdom, in the works based on that section of DisneyWorld. Jon Favreau is attached to that one.
