A Scanner Darkly(2006)
Set in the future, the film follows a group of drug addled, low-life friends in suburban California. "Reeves is the brooding special agent in a shape-shifter suit, assigned to spy on his own friends; Downey Jr is the sinister alpha male; Harrelson is the Lebowski-esque goofball. On one hand, it's a paranoid futuristic thriller, but on the other it's a portrait of life in deadbeat slackerdom." [Andrew O'Hehir].
