This early Tarzan film, produced without the backing of a major studio, is primitive and crudely made, and the story (written by Edgar Rice Burroughs himself!) is formulaic, but it has plenty of action, some impressive animal performances, and, in Buster Crabbe, a Tarzan who is both sturdy and nimble. Lots of beefcake here. It would be welcome news if the entire serial (this movie is only the first 4 chapters) was discovered some day. **1/2 out of 4.
