Potterton was born and raised in south London's Tooting Bec neighbourhood, the eldest of three children born into an entertainment-industry family—his father was a professional musician and his uncle was the manager of the London Palladium. By age five, he was attending the Saturday morning pictures, where he first became interested in film; by 14, he was getting regular work as a child actor in live-action films being shot at Ealing Studios, Elstree Studios and Pinewood Studios. He won a place to study art at the Hammersmith Academy; upon graduation, in 1949, he was drafted to fight in the Korean War. He spent two years in the Royal Air Force; after his discharge, a neighbour suggested that he apply at Halas and Batchelor, the studio which was doing the animation work for the film Animal Farm, which would be Britain's first animated feature. By this time, Potterton had an excellent art portfolio, including a comic book; he was hired and spent the next two years there as an assistant animator.

During this time, Potterton also founded the Grasshopper Group, a cooperative with the mission to help London's animators produce their projects. He met Norman McLaren, the Scottish animator who was already on his way to becoming the star filmmaker at the National Film Board of Canada (NFB). Potterton also wanted to leave London, which had become intolerably dirty—the 1952 Great Smog of London, which killed at least 4,000 people, had a deep impact on him. That, and McLaren's description of Canada and working at the NFB, led him to move to Ottawa in 1954. He was hired by the NFB; his first project was the 1955 animated training film Huff and Puff.^[2]

Between 1954 and 1960, Potterton worked on 10 films. In 1960, he was offered a job as a filmmaker at Lars Calonius Productions, one of the largest TV and commercial animation films in the USA. Potterton left the NFB, moved to New York and worked at the firm for one year; he disliked living in New York and returned to the NFB, which had moved its offices to Montreal. The next seven years would be extremely fruitful for Potterton; his 1962 short film My Financial Career would be nominated for an Oscar, as would his next film, 1963's Christmas Cracker. He was then assigned to film a comedic travelogue of Canada, in which Buster Keaton rides 4,000 miles in a Railroad speeder. The result was The Railrodder, which won multiple awards and remains a popular film.^[3]

In 1967, Potterton's NFB colleague George Dunning asked him to work on his film Yellow Submarine, then being produced to feature The Beatles. While in London, Potterton had the opportunity to interview the British playwright Harold Pinter and came up with idea of a documentary about Pinter and his sketches Pinter's People. Potterton pitched the result to NBC; it aired as NBC's Experiment in Television: Pinter People. The film won several awards, including a Peabody Award.

In 1968, Potterton founded his own company, Potterton Productions. He worked with various clients, notably Reader's Digest and Cinar, to produce several children's programs. The company produced Peter Sander's The Selfish Giant and Larry Kent's Fleur Bleue (The Apprentice) in 1971,^[4] as well as Mike Mills' The Happy Prince in 1974 and, in 1975, The Little Mermaid and The Christmas Messenger. He directed live-action and animated sequences for The Electric Company and Sesame Street; for the latter, he created the character of 'George the Farmer', who appeared in 18 episodes. He also had a large roster of ad agency clients for whom he produced commercials. By the mid-1980s, Potterton Productions was one of the largest independent production firms in Canada.^[5]

In 1981, Potterton was hired by producer Ivan Reitman to direct the animated feature Heavy Metal for Columbia Pictures. Potterton supervised all of the film's eight sequences, and the work of 65+ animators in Canada, England and the U.S. While reviews were mixed at release, Heavy Metal was the top-selling video for four consecutive weeks in the U.S. when it was released on video in 1998. It is now a cult classic.

In 1988, Potterton created and directed The Smoggies, a 53-episode animated series which aims to entertain and educate young children about environmental issues. It is still widely aired internationally.^[6]

In 1977, Potterton's friend Donald Pleasence made the children's album Scouse the Mouse. Ringo Starr was one of the voices on the album and he and Pleasence decided to write a companion book of the same name. Potterton was enlisted as its illustrator. In 1968, he had produced his own comedic illustrated book, The Star (and George); he would produce two more: In the Wake of Giants: Journeys on the Barrow and the Grand Canal (2008) and The Snowman: The Story of Joseph-Armand Bombardier in 2020.

Potterton was an accomplished landscape painter. He was also a life-long aircraft buff, and created large, accurate, highly detailed paintings of planes; just before he died, he'd completed a painting of the Memphis Belle.^[7] He directed local theatre productions, and was organizing a fundraiser, using The Rainbow Boys, which was filmed in Lytton, British Columbia–he hoped to raise funds to help the town re-build after the Lytton wildfire.^[8] He continued to produce cartoons; his last project was Peter Piper and the Plane People, which was completed by Pascal Blais.^[9] When he died, he was working on a live-action comedy called A Stage Too Far.

Potterton's first wife was film editor Judith Merritt; his second wife was producer Karen Marginson. He had three sons. After moving to Montreal in 1961, Potterton spent the rest of his life in Quebec; the Potterton Productions head office was his home, a farm near Cowansville, in Quebec's Eastern Townships. After suffering a stroke, he died at Cowansville's Brome-Missisquoi-Perkins Hospital on 23 August 2022, at age 91.
