Schlesinger sold his studio to Warner Bros. in August 1944. Edward Selzer was in turn named the new producer. By this time, Warner cartoons' top directors of the 1940s were Friz Freleng, Chuck Jones, Bob Clampett and recently Robert McKimson, who took over Frank Tashlin’s unit after he left the studio. Their cartoons are now considered classics of the medium. They directed some of the most beloved animated shorts of all time, including (for Clampett) "Porky in Wackyland", "Wabbit Twouble", "A Corny Concerto", "The Great Piggy Bank Robbery", "The Big Snooze", (for Freleng) "You Ought to Be in Pictures", "Rhapsody in Rivets", "Little Red Riding Rabbit", "Birds Anonymous", "Knighty Knight Bugs", (for Jones) "Rabbit Fire", "Duck Amuck", "Duck Dodgers in the 24½th Century", "One Froggy Evening", "What's Opera, Doc?", (for McKimson) "Walky Talky Hawky", "Hillbilly Hare", "Devil May Hare", "The Hole Idea" and "Stupor Duck".
