Drew Goddard is directing from a screenplay by Goddard and Joss Whedon, who is also producing. Details of the plot remain under wraps.
Production is underway and the film is scheduled to open wide through MGM on February 5, 2010.
'Finding this ensemble has been very hard and very rewarding,' Whedon said. 'Each of the kids is unique, fascinating and talented, and like true friends, the group is more than the sum of its parts.
'These are people you care about, able to go toe-to-toe with the amazing actors we've corralled thus far I can't wait to harm them.'
