During the mid-1960s, Menville and Janson co-produced a series of short live-action films, among them the Academy Award-nominated Stop Look and Listen, an innovative stop-motion pixilation experiment in which the main characters "drive" down city streets in invisible cars.
They followed Stop Look and Listen with their 1967 short film Vicious Cycles, a comedy shot in 16 mm, featuring a gang of hard-core bikers intimidating a motor scooter club.
Clips from the film were featured in a 1970 summer television series on the ABC network called The New Communicators and made Menville's pixilation technique famous in the USA.
They graduated to 35 mm with their next short film, 1970's Blaze Glory, a spoof of cliche western movies in which heroes and villains rode around the Old West, without horses.
In the mid-1970s, the team began a stint at Filmation, during which they brought their irreverent style to Star Trek: The Animated Series, writing two episodes: "Once Upon a Planet" and "The Practical Joker".
