"Tarzan the Ape Man" was the first of these, with Bo getting top billing as Jane, Richard Harris as Jane's father getting second, Cheetah the orangutan getting third and Miles as the title character getting fourth.

After a memorable turn in Blake Edward's "10" Bo Derek settled into a brief career of movies directed by her husband John Derek as a chance to showcase his wife's boobs. The orangutan who played Cheetah got taken on the publicity tour and Miles was not taken, presumably so he would not upstage Bo Derek. ".and people were throwing things at us and it was-a mess! And on the basis of that that I got the part." Originally Lee Canalito got the title role, and footage was shot of him as Tarzan, but ultimately Miles O'Keefe was brought in.

In 1992 Miles O'Keefe told Joe Bob Briggs on TMC's "Joe Bob Briggs' Drive-In Theatre" that the audition process for the title role in John Derek's "Tarzan the Ape Man" consisted of being dressed up in a wig and a loincloth with other Tarzan wannabes and taken to a park in LA where they were told to swing around in the trees and make noise.
