Reason to love Los Angeles #83: an active film community including everyone from studio bigwigs to literate fans. Both will be out in force this weekend when our quirkiest hometown cinematheque holds a 24-hour movie marathon.

Nonprofit movie programmer Cinefamily has spent the past five years establishing itself in the vanguard of diverse, intelligent programming. Godard, Cassavetes, art house, exploitation, horror, cult flicks--all that and more flickers here, cheered on by a cool multi-age crowd that sits on folding chairs and couches at Cinefamily?s 1940s movie house for silent-film revivals.

But now it?s all in danger, since studios have begun eschewing film prints in favor of new, expensive digital projection. So like Mickey Rooney before it, Cinefamily?s putting on a show: a 24-hour telethon with lots of surprises such as guests Robert Downey Jr. and John Hawkes, beginning tomorrow at 1 p.m.

If you can?t make the event, there?s a Kickstarter campaign to help pay for a digital projector and theater refurbishment. Donations are tax-deductible, and pledges of $50 include telethon admission. It?s the movie lover?s idea of charity beginning at home.

Cinefamily at the Silent Movie Theatre, 611 N. Fairfax Ave.; 323-655-2510 or cinefamily.org
