CANNES, France—Matt Damon said on Friday he had immersed himself for weeks in Oklahoma with oil rig workers for his role as a disoriented American who travels to France to help his jailed daughter, in a new film loosely inspired by the real-life Amanda Knox case.
Damon said he spent time driving around and living with the so-called roughnecks in Oklahoma to grasp his character’s mindset in “Stillwater”.
