There had been films of Wodehouse stories since 1915, when A Gentleman of Leisure was based on his 1910 novel of the same name. Further screen adaptations of his books were made between then and 1927, but it was not until 1929 that Wodehouse went to Hollywood where Bolton was working as a highly paid writer for Metro-Goldwyn-Mayer (MGM). Ethel was taken with both the financial and social aspects of Hollywood life, and she negotiated a contract with MGM on her husband's behalf under which he would be paid $2,000 a week. This large salary was particularly welcome because the couple had lost considerable sums in the Wall Street Crash of 1929.  The contract started in May 1930, but the studio found little for Wodehouse to do, and he had spare time to write a novel and nine short stories. He commented, "It's odd how soon one comes to look on every minute as wasted that is given to earning one's salary." Even when the studio found a project for him to work on, the interventions of committees and constant rewriting by numerous contract authors meant that his ideas were rarely used. In a 2005 study of Wodehouse in Hollywood, Brian Taves writes that Those Three French Girls (1930) was "as close to a success as Wodehouse was to have at MGM. His only other credits were minimal, and the other projects he worked on were not produced."  Wodehouse's contract ended after a year and was not renewed. At MGM's request, he gave an interview to The Los Angeles Times. Wodehouse was described by Herbert Warren Wind as "politically naive [and] fundamentally unworldly," and he caused a sensation by saying publicly what he had already told his friends privately about Hollywood's inefficiency, arbitrary decision-making, and waste of expensive talent. The interview was reprinted in The New York Times, and there was much editorial comment about the state of the film industry. Many writers have considered that the interview precipitated a radical overhaul of the studio system, but Taves believes it to have been "a storm in a teacup", and Donaldson comments that, in the straitened post-crash era, the reforms would have been inevitable.  Wind's view of Wodehouse's naivete is not universally held. Some biographers suggest that his unworldliness was only part of a complex character, and that in some respects he was highly astute. He was unsparing of the studio owners in his early-1930s short stories set in Hollywood, which contain what Taves considers Wodehouse's sharpest and most biting satire.
