Disney 's film studios stayed busy as well , averaging five or six releases per year during this period . While the production of shorts slowed significantly during the 1950s and 1960s , the studio released a number of popular animated features , like '' Lady and the Tramp '' ( 1955 ) , '' Sleeping Beauty '' ( 1959 ) and '' One Hundred and One Dalmatians '' ( 1961 ) , which introduced a new xerography process to transfer the drawings to animation cels . Disney 's live-action releases were spread across a number of genres , including historical fiction ( '' Johnny Tremain '' , 1957 ) , adaptations of children 's books ( '' Pollyanna '' , 1960 ) and modern-day comedies ( '' The Shaggy Dog '' , 1959 ) . Disney 's most successful film of the 1960s was a live action/animated musical adaptation of '' Mary Poppins '' , which was one of the all-time highest-grossing movies and received five Academy Awards , including Best Actress for Julie Andrews and Best Song for Robert B. Sherman & Richard M. Sherman for " Chim Chim Cher-ee " . The theme park design and architectural group became so integral to the Disney studio 's operations that the studio bought it on February 5 , 1965 , along with the WED Enterprises name
