One film won the majority of prizes last night at the SXSW Film Festival in Austin. The jury wholeheartedly embraced Natural Selection, a new indie feature that was written and directed by Texan Robbie Pickering. The NYU film school graduate has a track record that includes award-winning short films and commercials. The film is his feature directing debut.

Described as the story of a sheltered Christian housewife in Texas, Natural Selection depicts the drama that unfolds when the woman learns that her dying husband has an 23-year old illegitimate son. The film won numerous awards at last night's ceremony, including best narrative feature and the narrative audience award, as well as writing and acting prizes.

The popular film festival continues through the weekend in Austin with the event's 25th music festival opening tonight in the Texas capital.
