Owen Wilson, hospitalised after an apparent suicide attempt, has dropped out of the upcoming ensemble comedy 'Tropic Thunder', film industry trade papers reported on Wednesday.

Wilson will not appear in the DreamWorks movie, already six weeks into production in Hawaii, Daily Variety and The Hollywood Reporter said, citing sources they didn't identify.

The decision was characterised as a mutual agreement between director Ben Stiller and the 38-year-old actor, who was taken to the hospital on Sunday after police responded to the report of a suicide attempt at his Santa Monica home.

The Hollywood Reporter said Wilson had a minor part in the movie, which stars Jack Black and Robert Downey Jr. and revolves around a group of actors who find themselves in the middle of a war.

Wilson's part was to be filmed in just a week, the trade paper said.

Messages left early Wednesday for a DreamWorks representative and Wilson publicist Ina Treciokas seeking comment were not immediately returned.

Treciokas declined to answer questions on Tuesday about whether Wilson attempted to commit suicide.

Many Hollywood insiders believe Wilson's setback will be short-lived and that he will continue to enjoy big-screen success.

"Most people are confused by this, but as a recovering addict myself it gives me hope that this is his bottom and he can turn it around. He really is a good guy," friend Tom Arnold told theinsideronline.com.

"He's loved," Bernie Brillstein, a veteran Hollywood manager who worked with John Belushi and Chris Farley, said Tuesday.

Brillstein said the reported suicide attempt is "serious, but it's a singular case. Anyone can have a bad day, a very bad day."

Wilson's box-office track record 'Wedding Crashers' topped $200 million, 'Cars' brought in almost $250 million plus his on-screen image as an affable everyman who can charm the ladies while boozing with the boys has made him a favorite with both filmmakers and filmgoers.
