The film is based on a newspaper comic strip of the same name by Jim Lawrence and Jorge Longarón that debuted January 18, 1970 and ran in 80 to 100 papers. It was the first mainstream comic strip with a black lead character. The end credits thank Chicago Tribune Syndication, which licensed the comic strip to newspapers. Ironically, the movie was released after the strip ended in 1974.

Fancy's unusual white car is a 1972 Stutz Blackhawk. It was priced at around $26,000 (over $160,000 in 2021). The mobile phone cost an additional $1,500 to install (over $9,200 in 2021). The bodies were handmade in Italy, then shipped to the United States where they were mated with a Pontiac Bonneville engine and frame. Between 500 and 600 were made from 1971 to 1987. Elvis Presley bought the first one when the manufacturer could not make a deal with Frank Sinatra.
Producer/director Arthur Marks had plans to follow up this picture with a television series, according to an article in the 25 June 1973 edition of The Hollywood Reporter, but no such program was produced.
