Because writer/director Lena Dunham cast herself in the lead role of her impressive breakout film TINY FURNITURE and because she picked her real life mother and sister to play her character Aura’s mother and sister, and because she shot the whole thing in their family’s Tribeca loft, there was a tendency to assume it was an intensely autobiographical film. Maybe not. Aura was a directionless slacker. Dunham is anything but. Her new HBO series, Girls, debuts in April, while her first work as a co-writer, Ry Russo-Young’s NOBODY WALKS premieres later this month in competition at the Sundance Film Festival.
