Written by Dana Olsen and Audrey Wells, and starring Brendan Fraser, Leslie Mann, Thomas Haden Church, Holland Taylor, Richard Roundtree and John Cleese.

While touring Burundi with local guide Kwame and a trio of porters, San Francisco heiress Ursula Stanhope encounters her spoiled fiancé Lyle van de Groot, who wishes to take her home and had hired two poachers, Max and Thor, to track her down.

Max and Thor are deported, but resolve to return to the treehouse to capture Ape and make a fortune off of him in Las Vegas.

While Ursula is at work, George explores San Francisco on his own, and uses his vine-swinging skills to rescue a man whose paraglider has become caught on the suspension cables of the Bay Bridge.

Lyle has George subdued by a group of hired mercenaries, and forcibly takes Ursula to a boat waiting on Ape River to perform their marriage rites.

George is rescued from the mercenaries with help from Shep and the gorillas, and swings in to reach Ursula and Lyle, but crashes painfully into a massive tree.

As the tree falls over the river, George manages to pull Ursula to safety while the rapids lead Lyle into a dark cave.

Lyle, thinking Ursula is still in the boat, proclaims their wedding vows; to his horror, he discovers that he has just married himself to a gorilla, who kisses him.

George and Ursula declare their love for each other and marry, with the people of both San Francisco and Africa, as well as the jungle's animals, in attendance.

A mid-credits scene shows that Ape has moved to Las Vegas and become a famous singer, with a humiliated Max and Thor forced to be part of his performance.

Dana Olsen had written a spec script titled Gorilla Boy, a Tarzan parody that was told from Jane's point of view, depicted as a spoiled rich American girl.

Their faces were remote-controlled animatronic heads, which, along with the yak fur gorilla suits, were provided by Jim Henson's Creature Shop.

Walt Disney Home Video released the film on VHS, DVD and LaserDisc in the United States and Canada on December 2, 1997.

Most of the major characters were re-cast using different actors, although Keith Scott, Thomas Haden Church and John Cleese reprised their roles from the original.
