But Ritchie is hoping we're captivated by the mind games.
"Revolver" has been advertised with the tagline: "The greatest trick that he ever pulled was making you believe that he is you" -- a rip-off of the famous line from "The Usual Suspects" ("The greatest trick the devil ever pulled was convincing the world he didn't exist").
To Ritchie, the true enemy lies inside each of us, and it's only when Green realizes this that he's free. He laments that people are "approval junkies," and Liotta's character is left to symbolize this. In his parting shot, he cries pathetically in his underpants: "Fear me!"
