Matthew McConaughey has joined the ensemble cast of Tropic Thunder, the Ben Stiller-directed DreamWorks comedy.
The job amounts to an uncredited cameo, as McConaughey takes the role that Owen Wilson ankled after he was hospitalized, says Variety.
McConaughey joins a cast that includes Stiller, Jack Black, Robert Downey Jr., Nick Nolte, Bill Hader and Steve Coogan.
The film is about a group of actors who gather on a remote island to shoot a big-budget war movie and are forced to become the soldiers they are playing.
Tropic Thunder is shooting in Hawaii and McConaughey will shoot for a week.
