Judy Greer is set to star in Disney’s upcoming, highly secretive science-fiction movie Tomorrowland. Deadline reports that the Arrested Development and Archer star is in talks to join already-announced cast members George Clooney, Hugh Laurie, and Britt Robertson, making for Greer’s third movie opposite Clooney (after The Descendants and Three Kings). It’s also part of an incredibly busy year for the actress, who recently signed on to an as-yet-untitled FX comedy pilot and Dawn Of The Planet Of The Apes. Greer’s specific role remains a mystery, as with just about everything else about Tomorrowland. What is known is that it’s directed by Brad Bird and written by Damon Lindelof, and it’s been said to involve alternate dimensions, an Earth in peril, and robots. (But no aliens.) Tomorrowland is slated for release and demystification in December 2014.
