Beat the summer heat with a refreshingly star-free film festival. Dances With Films enters its ninth year with a host of talent-filled films, sans celebs. Why no familiar faces? Festival co-founder Leslee Scallon explains, "The other festivals are busy programming mostly celebrity oriented films. It's not that we're dissing celebrities, we're just giving films a chance to be seen that are getting squeezed out of the circuit." Offer your support July 21-27.
$10 (per ticket), $125 (festival pass). Laemmle Fairfax Theatre, 7907 Beverly Blvd., Los Angeles. (323) 850-2929. www.danceswithfilms.com .
