Looks like an interesting one for seeing the works of aspiring film makers, and could make for a fun night out in the Mission District. From FrozenFilmFestival.com:
The San Francisco Frozen Film Festival is held every summer in the heart of the Mission district in San Francisco at the Roxie Theatre. Filmmakers whose work is accepted into the festival are invited to come to the city by the bay in the dead of summer to screen and discuss their work.
In addition to our annual international film festival, the SFFFF Youth Program is specifically focused on demonstrating to underserved youth that existing pathways do exist to help them find a career in the film arts. SFFFF holds annual music and art performances, as well as youth programming and awards presentations.
