Jan-Michael Vincent is Nanu, a jungle boy living in Africa who is discovered and brought to America by a school coach so as to participate in the sport of track and field.

This Disney comedy also starred John Amos, Tim Conway, Roscoe Lee Browne, Billy DeWolfe and Nancy Walker.

John Amos would later appear as Seth in The Beastmaster (1982) starring Marc Singer.

Jungle scenes were filmed at Caswell Memorial State Park and the Stanislaus River located near Ripon, California.

Nanu's pet tiger is explained in the film to have been born in India as the species is not native to Africa.

Jan-Michael Vincent previously appeared as Lincoln "Link" Simmons in the live-action 36 chapter cliffhanger serial Danger Island featured on the 1968 Saturday morning TV series The Banana Splits.

In the 1976 horror film Shadow of the Hawk Jan-Michael Vincent played the grandson of a Native American shaman... and in 1989 he was the villian to Tarzan (Joe Lara) in the made-for-television film Tarzan In Manhattan.

Jan-Michael Vincent passed in 2019 at the age of 74.
