With producer William L. Snyder, Deitch co-produced and directed a series of TV shorts of "Krazy Kat" for King Features from 1962 to 1964. "The Bluffers", which was based on one of Deitch's ideas, was also co-produced by him. He directed the 1966 film "Alice of Wonderland in Paris". In 1966, he worked with Czech animator Jiří Trnka on a feature-length animated film adaptation of "The Hobbit". However, producer William L. Snyder couldn't secure the funds, and in order to not let the rights for the novel expire, he asked Deitch to produce a short film adaptation in 30 days. Deitch and illustrator Adolf Born made a 13-minute animated film never intended for distribution; the film was long considered lost until it was rediscovered by Snyder's son and released on YouTube in 2012. Also in 1966, Deitch created a young girl adventurer in "Terr'ble Tessie."
