  Len Janson is an American writer and director whose career in animated cartoons and live-action motion pictures spanned several decades beginning in the 1960s. He began work as an in-betweener at the Walt Disney cartoon studio. By 1965 he had become a story man with his first screen credit in Rudy Larriva's Boulder Wham!. Soon after, he teamed with Chuck Menville to produce a series of live-action films which used the pixilation technique. An example is Stop Look and Listen. By the early 1970s, Janson and Menville had become major names in the animation industry and welcome storytellers at studios such as Filmation and Hanna-Barbera. Their partnership ended with Menville's death in 1992. Janson remained active for a few more years, mainly as story editor for Sonic the Hedgehog. He also wrote episodes of Baywatch Nights.
