Walt Disney
Stevenson worked for the Disney Company in 1956 for six weeks and ending up making 19 films in 20 years. His early credits were Johnny Tremain (1957), a story set in the American Revolution, and Old Yeller (1957), a boy and his dog tale. In 2019, Old Yeller was selected by the Library of Congress for preservation in the National Film Registry for being "culturally, historically, or aesthetically significant".
Stevenson did episodes of Disney's Zorro, then directed a film about Ireland, Darby O'Gill and the Little People (1959), and an adaptation of Kidnapped (1960). He had a commercial success with the comedy The Absent-Minded Professor (1961) and the adventure film In Search of the Castaways (1962). Son of Flubber (1963) was a popular sequel to The Absent-Minded Professor, and The Misadventures of Merlin Jones (1964), a teen comedy, was an unexpected hit, leading to a sequel, The Monkey's Uncle (1965).
None did as well at the box office as Mary Poppins (1964), which gained domestic rentals of $45,000,000 and won five Oscars.
Also among Stevenson's Disney films was the Hayley Mills comedy That Darn Cat! (1965). Stevenson and Disney focused on comedies: The Gnome-Mobile (1967) with Walter Brennan, Blackbeard's Ghost (1968) with Peter Ustinov and Dean Jones, and The Love Bug (1968) with Jones, which was another hit.
Bedknobs and Broomsticks (1971) was an attempt to repeat the success of Mary Poppins. Stevenson directed Herbie Rides Again (1974) with Ken Berry and Helen Hayes, and the adventure story The Island at the Top of the World (1974). One of Our Dinosaurs Is Missing (1975), with Hayes and Ustinov, was a comedy. Stevenson's last feature was The Shaggy D.A. (1976) with Dean Jones.
In July 1977, Variety reported that his track record at Disney made him "the most commercially successful director in the history of films." At the end of 1976, he had 16 films on Variety's list of all-time domestic rental films, more than any other director at the time, with the second most successful having only 12. The Shaggy D.A. was to become his 17th, all being Disney films. The total US and Canadian rentals for these 17 pictures was $188,000,000, which Variety said translated into roughly $250 million in world rentals or an estimated world box office gross of $750 million.
