Arthur Davis meanwhile directed a plethora of cartoons featuring minor or one-shot characters, such as A. Fox, Wellington the Dog, Elmo the Mouse, Blackie and Daisy Lou, Louie the Parrot And Heathcliff the Cat, Slug McSlug, Pierre the Termite and I.M.A. Sureshot, Bluebeard and among others. His unit was shut down in 1949 by Warners due to budget issues, causing him to move to Freleng's unit to become one of his key animators. In 1948, Warners could no longer force theaters to buy their movies and shorts together as packages, due to the United States v. Paramount Pictures, Inc. anti-trust case that year. It resulted to shorts of the early 1960s to have tighter budgets. Edward Selzer in 1958, retired, leading to production manager John Burton to take his place. David DePatie assumed producer in 1960 after Burton left the studio. After more than two decades at the top, Warner Bros. shut down the original "Termite Terrace" studio in 1963 and DePatie-Freleng Enterprises assumed production of the shorts, licensed by Warner Bros. Most of the series’ main cast of characters were retired from theaters at this time, including Warners most popular star, Bugs Bunny. Daffy Duck however, would still appear in theatrical cartoons, mostly paired with Speedy Gonzalez. Beside them, Porky Pig, Granny, Sylvester and the Goofy Gophers appeared in this era, but most appeared in just one or more shorts.  14 Wile E. Coyote and Roadrunner cartoons were also commissioned, with the last 11 being outsourced to Format Films, under direction of former Chuck Jones animator Rudy Larriva. These cartoons were not well received, and were criticized for its lack of spirit and charm to that of Jones’ shorts. After DePatie-Freleng ceased production of "Looney Tunes" in 1967, Bill Hendricks was put in charge of production of the newly renamed Warner Bros.-Seven Arts animation studio, and hired veterans such as Alex Lovy and LaVerne Harding from the Walter Lantz studio, Volus Jones and Ed Solomon from Disney, Jaime Diaz who later worked on "The Fairly OddParents" as director, and David Hanan, who previously worked on "Roger Ramjet". Hendricks brought only three of the original "Looney Tunes" veterans to the studio; Ted Bonniscken, Norman McCabe and Bob Givens.
