unsuccessful, falling $1 million short of the production budget. Upon his return, Walt started planning the construction of an amusement park called Mickey Mouse Park on an eight-acre (3.2 ha) site near the studio; its attractions would include a steamboat ride but business interrupted the plan and production for a third British film The Sword and the Rose began. Walt supervised the film's production, which was financed by a new subsidiary called Walt Disney British Films Limited. According to Walt, he had the idea of an amusement park during a visit to Griffith Park with his daughters. He said he watched them ride a carousel there and that he thought there "should be ... some kind of amusement enterprise built where the parents and the children could have fun together". Walt changed the planned amusement park's name to Disneylandia, then to Disneyland. Because Roy was doubtful about the park, Walt formed a new company called Walt Disney Enterprise on December 16, 1952, to fund the park. Shortly after, its name was changed to Walt Disney Incorporated, and again to WED Enterprises (now Walt Disney Imagineering) in November 1953. He hired a group of designers to work on the plans; these became known as "Imagineers". Walt and his friends visited parks in the U.S. and Europe to get ideas on how to build one. His plan to build the park in Burbank near the studio quickly changed when he realized that 8 (3.2 ha) acres would not be enough land. Walt acquired 160 acres (65 ha) of orange groves in Anaheim, southeast of Los Angeles in neighboring Orange County, at $6,200 per acre to build the park. Construction on the park began on July 12, 1954; Walt wanted it to be completed by 1955, with storytelling attractions and areas, as well as being clean and perfect. By the time the park opened, it cost the company $17 million to construct. In February 1953, Disney's next animated film Peter Pan was a financial success but Walt wanted to improve the standard of animation without raising the cost. When Disney wanted to create The Living Desert, a feature with two short films, for the True-Life documentary, RKO's lawyer believed it would break the 1948 antitrust Supreme Court ruling if it was sold as a package. Roy thought the company would thrive without RKO and Disney created its own distribution company Buena Vista Distribution,
