I suspect that the title of this production, "The New Adventures of Tarzan," has been confusing to some folks since it was only "new" in 1935 when Edgar Rice Burroughs himself produced it!
What we have here is an old "cliffhanger" of twelve episodes which were originally shown at theaters, one week at a time, to run alongside main feature films. The idea was to keep you "hanging" so you'd come back the next week to see what happened -- someone was always about to be heinously knocked off at the end of each episode, (except for in the last one).
The story is this: Tarzan and his companions, headed by Major Martling, go head-to-head in the Guatemalan jungle against the nefarious P.B. Raglan in an effort to secure "The Green Goddess," a priceless ancient artifact which also contains the formula for a super-explosive. Of course, the Green Goddess is in the hands of first one and then another of the two factions and it becomes clear that only Tarzan can finalize its possession for the good guys. There is also a sub-plot of Tarzan going to the region for the priority purpose of rescuing his old friend, d'Arnot.
This film was actually shot on location, for the most part, in Guatemala where the action is supposed to have taken place so that is a big plus of this film. Herman Brix, a 1928 Olympic shot-putter, plays Tarzan but he later changed his name to Bruce Bennett and went on play roles in films like "Treasure of the Sierra Madre" (1948) and, "Sahara" (1943). His "Tarzan yell" sounds a great deal like Minnie Pearl's "How-deeee!!!" but, other than that, he makes for a pretty believable jungle hero.
The episodes of the serial are entitled:
1. New Adventures
2. Crossed Trails
3. Devil's Noose
4. River Perils
5. Unseen Hands
6. Fatal Fangs
7. Flaming Waters
8. Angry Gods
9. Doom's Brink
10. Secret Signals
11. Death's Fireworks
12. Operator No. 17
This particular print has been digitally re-mastered and marketed by the Columbia River Film Group. Of course, the film is shot in black and white, full-screen, and runs for a total of FOUR HOURS! It's all on a single DVD and, having owned this serial issued by a couple of different distributors, this particular one is as good as it gets, a fairly clear print with decent sound. The film is in the public domain so it can be copied and sold by anyone and inferior copies abound.
This serial was later heavily edited to produce the film, "Tarzan and the Green Goddess" (1938), which only runs for a total of 90 minutes. The serial version is by far the superior choice of the two productions if you are really into the older black and white adventure films.
Highly recommended to appropriate audiences.
