LOS ANGELES - Owen Wilson, who was hospitalized Sunday following a reported

suicide attempt, is no longer scheduled to appear in "Tropic Thunder," an ensemble comedy in which he had a supporting role.

The DreamWorks production, headlined by Jack Black and Robert Downey Jr., concerns a group of actors who find themselves in the middle of a war. The film is in its sixth week of production under Ben Stiller's direction, sources said, and Wilson had not begun shooting his part.

Wilson, 38, is hospitalized at Cedars-Sinai Medical Center near Beverly Hills after fire and police personnel went to his Santa Monica home in response to an emergency call Sunday.

A call log published by the Santa Monica Police Dept. indicated that there was a suicide attempt at the address. A statement attributed to Wilson has "respectfully" asked the media to allow him to "receive care and heal in private during this difficult time."
