27 Dresses star Judy Greer is in talks to join George Clooney and Hugh Laurie in Disney's mysterious science-fiction flick, Tomorrowland.

Judy's character remains unknown as part of attempts to keep details of the sci-fi motion picture closely protected, according to Deadline.

If Greer lands the role it will mark the third time the 38-year-old actress acts opposite Clooney, after 1999's Three Kings and 2011's The Descendants.

The movie, which will be scripted by Damon Lindelof and Jeff Jensen, already stars Hugh Laurie, Britt Robertson and Raffey Cassidy.

Laurie has been confirmed to play villain David Nix, while Clooney will portray grizzled inventor, Frank Walker.
