The signature "Tarzan yell" is provided by Brian Blessed, the voice of this movie's villain Clayton. because after noticing that Tony Goldwyn could not make a convincing scream, Blessed went to one of the producers to tell him that he could do it, the producer refused at first but after he yelled in front of him, he accepted without hesitation.

The noises the gorillas make are sounds of chimpanzees. Gorillas' vocalizations are mainly roars, growls, and grunts.

During the Walt Disney Pictures opening logo, the background turns into that of a jungle.

In most foreign prints of the movie (specifically the European Spanish and German versions), "Son of Man" and "Strangers Like Me" replace "You'll Be In My Heart" and "Two Worlds", respectively, in the credits.
