LOS ANGELES  On weekdays, Ivar Avenue is a quiet strip of Hollywood, with a theater, a recording studio, a Jack in the Box, a gay and lesbian elderly housing complex and a film school. Every Sunday morning, it becomes the Hollywood Farmers Market, four bustling blocks of farm and food stands offering everything from oyster mushrooms to California sea bass to a crowd of 8,000 people.

But after 19 years in existence, the Hollywood Farmers Market is endangered, at the center of a fight that has put on display three of this city’s most powerful passions: Food, film and parking. The Los Angeles Film School, a relative newcomer to what was once a seedy pocket of Hollywood, has moved to prevent the market from renewing its permit because farm stands obstruct the driveway to its most convenient parking lot.

“We do support the market; we want it to continue to operate,” said Antoine Ibrahim, a spokesman for the film school. “But what we did was ask them to tailor their configuration so we can have our street back.”

This dispute has set off a food firestorm that is playing out in Facebook postings and Twitter feeds  and even, testifying to the demographics of some of the clientele, in paper petitions that were being passed out at the market on a recent Sunday. Between weighing heirloom tomatoes (yes, they are still in season here), farmers handed out T-shirts reading “Save the Hollywood Farmers Market” and urged customers to put them on before the television cameras arrived.
