“I don’t know who I am,” former heavyweight champ Mike Tyson says to N.Y. Times contributor Tim Arango in a 5.11 piece about James Toback‘s Tyson, a pared-down but altogether touching doc that will show later this week in Cannes. “That might sound stupid,” Tyson continues. “I really have no idea. All my life I’ve been drinking and drugging and partying, and all of a sudden this comes to a stop.”

The line this most recalls, of course, is the one from Wim WendersThe American Friend, spoken to Dennis Hopper‘s Tom Ripley character: “I know less and less about who I am, or who anyone else is.”
