|That nice butt belongs to Jane (Maureen O'Sullivan) from the censored scene|
Cheetah, of course, was the Johnny Weissmuller Tarzan sidekick, the same Tarzan who swam naked in "Tarzan and His Mate" in 1934. At the time, individual states had the say-so about censorship. Shortly thereafter, the Hayes Commission took all sex out of American movies and made them faux virtuous--except for all the killing and general mayhem.
Here's a look at the Tarzan nude scene, which right-wingers forced off the screen and into a vault for many years (but they let Cheetah stay up there for us to admire, bless 'em). Jane, you will note, has a nice ass.
