On February 25, 1939, the architect Frank Lloyd Wright visited the studio with a copy of the Russian animated movie "The Tale of the Czar Durandai" (1934), directed by Ivan Ivanov-Vano, which he showed to the artists, among them Hubley. Wright thought that the different style and design, that was very different from the typical Disney animation, would inspire and give the animators new ideas. Hubley liked what he saw and was influenced by it. He left the company during Disney animators' strike in 1941, and found work directing films for Screen Gems and the Army's First Motion Picture Unit until he joined United Productions of America which was founded by Stephen Bosustow, Zack Schwartz, Dave Hilberman. UPA soon became known for their highly stylized designs and limited animation.
