Raffill was born in England. He grew up in the Midlands near Coventry, and spent a lot of time on his uncle's farm. He worked with horses and wanted to be a jockey but was too tall. When he was 18 years old, he moved to the United States.
Raffill broke into the film industry as an animal supervisor, eventually owning his own company which would rent out animals to film and TV show. He did this on such films as The Lion (1962), Lt. Robin Crusoe, U.S.N. (1966) for Disney, Tarzan and the Valley of Gold (1966), and Monkeys, Go Home! (1967), again for Disney, as well as the TV series Tarzan (1966-68).
Raffill made his feature debut as director with The Tender Warrior (1971), starring Dan Haggerty. Raffill also helped write and produce, and handle animals. It was shot at the Okefenokee Swamp in Georgia. Raffill sold it to Warner Bros, was unhappy with what they did with it, bought it back, and re-distributed it.
The Adventures of the Wilderness FamilyEdit
Raffill wrote and directed The Adventures of the Wilderness Family (1975) with Robert Logan which was a popular success, leading to two sequels, and established Raffill as a maker of family adventure films with animals.
Raffill wrote and directed High Risk (1981), shot in Mexico, which he later described as a personal favorite. The film was not widely distributed but it got him the job of writing and directing The Ice Pirates (1984), made for John Forman and David Begelman at MGM on a budget of $8 million.
Raffill directed and wrote Mac and Me (1989), made to provide royalties to the McDonald's Foundation and to have a lead with spina bifida, which became a cult favorite and won Raffill a Golden Razzie for Worst Director. 
He moved into directing for TV with The New Adventures of Robin Hood and did the TV movie The New Swiss Family Robinson (1998) with Jane Seymour and David Carradine, which he also wrote. He directed Grizzly Falls (1999) with Bryan Brown.
Raffill directed episodes of Pensacola: Wings of Gold and 18 Wheels of Justice, and the movies A Month of Sundays (2001), Survival Island (2005), Croc (2007), Bad Girl Island (2010) and Standing Ovation (2010).
In 2018, Raffill's debut novel, Rage was published.
