VIDEO : SXSW: Ansel Elgort, Jon Hamm Rev Up Edgar Wright's 'Baby Driver'

Edgar Wright?s high-octane action film Baby Driver on Saturday roared into its rowdy world premiere at SXSW in Austin, Texas, with cast members Jon Hamm, Ansel Elgort and Eiza Gonzalez on hand to promote the film. The action-crime musical pic, which received raucous applause at its close, is the first feature that Wright wrote solo, and as a film that?s strong on action and slightly lighter on comedy, it stands out from the other titles on his résumé, including Shaun of the Dead and Hot Fuzz. Baby Driver tells the story of a young and innocent getaway driver, Baby (Elgort), who gets caught up with a crime boss (Kevin Spacey) and his gang of criminals (Hamm, Gonzalez and Jamie Foxx, to name a few). Due to an accident, Baby has never-ending tinnitus, and must drown out the noise with constant music. Baby Driver is set to open Aug. 11.
