Erik Singer, a dialect coach, was shown clips from 32 famous actors playing roles that required them to adopt an accent. He critiqued each one. As you might expect, Meryl Streep, Daniel Day Lewis, and Philip Seymour Hoffman get top marks. Tom Cruise and Kevin Costner, not so much. The worst? Not Dick Van Dyke's Cockney accent in Mary Poppins. It's Mickey Rooney's ridiculous Japanese accent in Breakfast at Tiffany's. This video was directed and edited by our friend, Joe Sabia.
