HOLLYWOOD (Variety) - Edward Asner, Joni Mitchell and Kenny Loggins are among the well-known Hollywood names lending their talents to a documentary opposing development of Playa Vista, future home of DreamWorks.

"The Last Stand: The Struggle for Ballona Wetlands" centers on the possibility of saving one of southern California's last wetland ecosystems and Los Angeles' largest remaining open space. Asner narrates the 56-minute film; Mitchell, Loggins and Joe Walsh provided music.

Developers of Playa Vista, a coastal site near Los Angeles International Airport, are planning a huge commercial and residential complex that will include a $200 million studio for DreamWorks.

The film will have its West Coast premiere Tuesday at the Museum of Tolerance in West Los Angeles. The world premiere took place at the Hawaii International Film Festival in November.
