Working in an oft-traversed realm, Gran Turismo director Neill Blomkamp and writers Jason Hall and Zach Baylin have delivered a racing car drama that’s rather different from the others. With plenty of potent auto action, some well-defined characters and welcome fresh components, this is an engaging look at people who overcome their own doubts and perceived shortcomings to help pull off something genuinely unusual. It’s a lively, spunky piece of work with no pretenses and all the more welcome for that. Originally dated for August 11, Sony pivoted amid the actors strike, and is sneak previewing the next two weekends, with the official wide opening on August 25.
