Filmmaker Danny Perez, probably best known around these parts as a frequent collaborator of Animal Collective and director of their short film ODDSAC, is preparing to release his debut feature film. It's called Antibirth, and it's being described as a "punk-rock horror movie." Starring Natasha Lyonne and Chloe Sevigny, it involves a woman who becomes pregant which leads to horrific-looking complications. Here's the official synopsis:

Hard-drinking, pill-popping, bong-ripping Lou (Natasha Lyonne) and her best friend Sadie (Chloë Sevigny) spend their days adrift in a druggy haze. But one wild night out becomes a bad trip that never ends when Lou wakes up with symptoms of an unexplained, highly abnormal pregnancy. Who—or what—is growing inside her? As her due date approaches with alarming swiftness, the fear, paranoia, and conspiracy theories begin to pile up. Spiked with blasts of hallucinatory color, surreal shocks, and subversive comedy, the audacious feature debut from Danny Perez is a no-holds-barred descent into delirium.

The trailer is pretty insane, with Danny's background in experimental filmmaking looking like it will be prominent in his first horror movie. As The Hollywood Reporter wrote when the film screened at Sundance earlier this year:

Perez takes his stylistic cues from visual techniques he developed while working with alt-popsters Animal Collective on music videos and performance installations, as well as ODDSAC, an experimental, hour-long film that he created for the band, which also screened in Sundance’s 2010 edition of New Frontier. Sequences throughout Antibirth that rely on moody lighting and disorienting SFX reinforce the episodes of confusion and dislocation that Lou and Sadie experience

Antibirth was picked up by IFC films after that Sundance bow, and will see a release on September 2, theatrically and on VOD. Check out the (NSFW) trailer below.
