Publicity for this movie during its original theatrical film release declared that the Walt Disney Pictures studio was planning a follow-up film to this pic to also star again actor Jan-Michael Vincent but this sequel never eventuated.
Scenes featuring the African country of Zambia were not shot there but in fact were filmed at the then 487 acre Lion County Safari Park south of Disneyland in Southern California. The jungle sequences were shot at the Caswell Memorial State Park near Ripon, California.
The scenes where Milo Jackson (Tim Conway) is shrunk to miniature size were extremely expensive to shoot during the time the film was made due to then big cost of constructing such very enormous props. The gigantic telephone itself cost US $7,900 to make whilst the woman's handbag and its chattels totaled to US $15,000.
This Disney movie's high-concept of recruiting an athlete from Africa was later used around twenty-one year's later for the 1994 basketball comedy The Air Up There (1994) which was released through Disney's adult production-house brand of Hollywood Pictures.
Jan-Michael Vincent said of this movie in its publicity: "It's a spoof. It was like making a film with real people. I played a nut in Going Home (1971) and a killer in The Mechanic (1972) and now it's fun to do something a little more positive. It sounds like a typical 'Me nanu, you Jane' movie but it's far more interesting than that".
