Chad Clinton Freeman just can’t say no. That’s one of the main reasons his PollyGrind film festival has expanded in its second year to span 10 days and more than 100 shorts, features, trailers and music videos. Last year’s version, held in May at the Sci Fi Center, exceeded Freeman’s expectations, and his modest project has grown into something more substantial.

“Last year I thought it was mostly going to be me showing filmmakers that I know, but it ended up being so much bigger,” he says. This year, the celebration of underground grindhouse cinema, encompassing horror, action, exploitation and more, received upwards of 500 submissions.

In addition to the expanded slate, PollyGrind is also switching venues this year, from the Sci Fi Center to Theatre 7 in the arts district, where Freeman is also the head of programming. “PollyGrind’s all about experimenting and looking at things in different ways, and that’s totally in line with Theatre 7,” Freeman says. It was while looking for a new space for the festival that he got involved with Theatre 7 in the first place, and now his love for underground and experimental filmmaking informs all of the venue’s programming.

PollyGrind is a little more extreme than the average night at Theatre 7, though, and Freeman prides himself on finding some of the most challenging and envelope-pushing movies around.

“A lot of these films, they haven’t played other festivals, or they’ve been rejected by a lot of other festivals,” he says, but he also notes that many PollyGrind selections go on to wider distribution. Last year’s top audience-award winner, Dead Hooker in a Trunk, was recently released on video on demand by IFC Films. The next down-and-dirty grindhouse classic just may be playing at this year’s festival.
