Sidetrack Films has partnered with Nike Sportswear for the upcoming release of Aaron Rose and Joshua Leonard‘s “Beautiful Losers,” the documentary that debuted earlier this year at the SXSW Film Festival. While the filmmakers and Sidetrack entertained traditional offers from distributors after the film’s Austin premiere, they decided instead to release the film on their own. The shoe and apparel company will assist in funding a five market launch for the film. The doc won the Documentary Jury Award at 2008 Cinevegas and opens this Friday at New York’s IFC Center, before a roll-out.
