The ninth movie in the Johnny Weissmuller Tarzan series (and third since the series moved from MGM to RKO) is also the first to feature an actress besides Maureen O'Sullivan playing Jane. In the first two RKO films, Jane was off helping with the war effort in England. Now it's time for her to come home but, alas, O'Sullivan wouldn't return to the part so it was recast with Brenda Joyce. Maureen is certainly missed but Brenda does a decent job and would play Jane for the remainder of the Weissmuller films. As I said, Jane returns home to Africa but she doesn't come alone. She brings with her some archaeologists who are interested in the lost city of the Amazons, a tribe of women warriors. Tarzan knows where the city is but won't tell them. If you've seen even one Tarzan movie before this, you should know the outsiders won't leave it alone. They convince Boy to lead them to the Amazon city, where they are not greeted with open arms.
I noticed Johnny Sheffield, the actor playing Boy, is in the middle of puberty by this point and his voice is noticeably deeper than the last film in the series. It's the sort of thing you probably only notice when you watch the series back to back. Sheffield's enjoyable, though Boy's a bit of a brat in this one. Cheeta, the series' regular scene stealer, is great as always. Henry Stephenson plays the kindly old lead archaeologist who has no clue how rotten his friends are. Barton MacLane makes a particularly slimy heavy. The Amazons are lovely young women in skimpy (for the time) outfits. Nothing wrong with that. Pretty Shirley O'Hara is the one given the most to do. Their leader is the awesome Maria Ouspenskaya. She's always a treat to watch. Nice sets and matte paintings. The Amazon stuff is lots of fun. As with all of the RKO Tarzan movies, this is a solid escapist adventure film. Nothing deep but good to watch on a lazy weekend.
