Can You Tell Leonardo DiCaprio & Brad Pitt Apart Despite Their New Movie Poster?

Leonardo DiCaprio and Brad Pitt, along with Margot Robbie, are teaming up with Quentin Tarantino for "Once Upon a Time in Hollywood," a "story of an LA and a Hollywood that don't exist anymore," according to the director, with the 1960s and the Manson Family as its backdrop. The movie poster has been released, featuring Pitt and DiCaprio as their respective characters, Cliff Booth and Rick Dalton; Robbie will be hitting the big screen as the late actress Sharon Tate. The film will also act as the late Luke Perry's final film role (the actor passed away earlier this month following a stroke). Are Pitt and DiCaprio interchangeable to you, or can you tell them apart?
