LOS ANGELES (Reuters) - Computers and photographs related to the production of director Steven Spielberg's highly anticipated "Indiana Jones" film have been stolen, the Los Angeles Times reported on Wednesday.

The paper said DreamWorks Pictures SKG, the studio co-founded by Spielberg, had asked local law enforcement to investigate. It quoted Spielberg's spokesman as saying the director was concerned the thieves might try to sell the materials.

"We want to warn the media that anything that is offered is stolen property," Marvin Levy told the paper. "We know it is out there."

Levy said the crime had occurred fairly recently, but did not know any specifics.

"Indiana Jones and the Kingdom of the Crystal Skull," the fourth movie in the adventure franchise, will be released next summer, 19 years after the last installment in the series.

Harrison Ford returns in the title role, joined by rising star Shia LaBeouf and Australian actress Cate Blanchett.

DreamWorks has a distribution deal with Paramount Pictures, a unit of Viacom Inc.
