Steve McQueen doubles the excitement in roles that match his steely persona. In Bullitt (Side A), gritty police procedure combines with volatile action as McQueen's Det. Frank Bullitt goes after the killers of a key witness and grabs the wheel of his Mustang for a wild chassis-slamming, whiplashing car chase through San Francisco. Peter Yates (Breaking Away) directs. McQueen plays the indomitable title character in Papillon (Side B), the powerfully visual adventure of a prisoner who vows to escape the inescapable: Devil's Island. Dustin Hoffman turns acting chameleon as Papillon's scruffy convict pal. Franklin J. Schaffner (Patton) directs.
