In 1935, the new film studio Photo Chemical Laboratories, known as P.C.L. (which later became the major studio Toho), advertised for assistant directors. Although he had demonstrated no previous interest in film as a profession, Kurosawa submitted the required essay, which asked applicants to discuss the fundamental deficiencies of Japanese films and find ways to overcome them. His half-mocking view was that if the deficiencies were fundamental, there was no way to correct them. Kurosawa's essay earned him a call to take the follow-up exams, and director Kajirō Yamamoto, who was among the examiners, took a liking to Kurosawa and insisted that the studio hire him. The 25-year-old Kurosawa joined P.C.L. in February 1936.
