The Formula One documentary 1 was first shown in Austin last year in advance of the inaugural US Grand Prix. Speaking to more F1 personalities than have ever been put in one film together, from John Surtees, Jackie Stewart and Jacky Ickx to Sebastian Vettel, Max Mosley and Martin Brundle, and produced by an award-winning crew of documentary makers, 1 focuses on the sport's safety and how it has moved on from the deadly game of the sixties and seventies to a far safer endeavor today.

If you missed it in Austin you'll your chance again soon: ten days after Ron Howard's F1 thriller Rush hits the big screen, 1 will be hitting iTunes and onDemand. You can watch the trailer for 1 below, as well as an interview from last year with the documentary's director and one of the producers on a local Austin news program.
