?Life outside the mainstream’ theme runs through Chicago Underground Film Festival, Aug. 15-19

The 14th Annual Chicago Underground Film Festival returns with “exceptionally strong documentaries, the usual lineup of cult films, and quite a bit of sex in the features,” said CUFF founder and festival director Bryan Wendorf.

CUFF runs Aug. 15-19, moving this year to non-traditional venues in Wicker Park: the Chopin Theater and Elegant Mr. Gallery.

“One trend in the films is people making unusual lifestyles, choosing live outside the mainstream,” noted Wendorf.

“Orchard Vale,” by Chicago rocker Tim Kinsella of Make Believe, Joan of Arc and Owen, opens CUFF with its world premiere tale of a family holed up in a suburban home after peak oil has brought the world to a quiet standstill.

“Tim’s an incredibly talented musician, and in ?Orchard Vale’ he’s taking the same sort of risks that he does in his music,” Wendorf said.

With Nate Ozark, Dean DeMatteis, Melina Paez, Cyan Walker and Joe Proulx. Aug. 15 at 8 p.m. at the Chopin Theater.

At press-time the “Orchard Vale” screening was close to selling out and Wendorf was considering a second screening on Aug. 15.

An after party at 10 p.m. Aug. 15 features David Daniel and Doug McCombs (of Tortoise), and Serpents and Tongues. At AV-aerie, 2000 W. Fulton Ave.
