The World's Greatest Athlete is a 1973 American sports comedy film directed by Robert Scheerer and starring John Amos, Roscoe Lee Browne, Tim Conway, Dayle Haddon, and Jan-Michael Vincent.

While out on a safari, the pair catch sight with their guide Morumba of the Tarzan-like jungle boy named Nanu (Jan-Michael Vincent), who can outrun a cheetah in full bound.

Seeing this, the coaching staff quickly whip out their recruitment pen and papers, but soon fall (literally) into the clutches of Nanu's godfather, spiritual leader Gazenga (Roscoe Lee Browne).

From this point forward, the plot is driven by a combination of slapstick and suspense, for Nanu's destiny as the World's Greatest Athlete will annoy several powerful people who are used to getting their way.

Nanu's innocence, Archer's scheming, Jackson's ineptitude, Gazenga's outraged wisdom, and the Machiavellian plotting of the villains all play roles in the action as the film heads toward the final track meet.

The film also features many prolific athletes and sports journalists in small or cameo roles, including Howard Cosell, Frank Gifford, Jim McKay, Bud Palmer, Joe Kapp, and Bill Toomey.

Upon the film's release, A.H. Weiler of The New York Times wrote: "It's a dream that is more often simple-minded than simple and generally as hilarious as finishing fourth in the mile run.
