I bought this on DVD and became an instant Herman Brix fan. Though his acting is somewhat stiff (to be generous), I can see why Edgar Rice Burroughs--Tarzan's creator--found Brix to be the "perfect" Tarzan. His build is spot-on, and he excels in the action scenes. If only he made more Tarzan films. Though this entry appeared in both serial form and as an edited feature, I recommend the serial version. The feature version is simply too choppy to have any story thru-line. However, the editing is slow with story pacing to match, in the serial. If you're a Tarzan fan (of the books, especially)--you'll find that this Tarzan is not the mono-syllabic dunce Hollywood liked to dish up--a welcome take on the character.
I watched the serial over several days--it's simply too long to take in one sitting--and I thoroughly enjoyed it. It takes some patience to keep your finger off the fast-forward button, but each chapter featured an action sequence that was usually worth watching. It's not for general consumption--most would find the quality too low to be very entertaining, but if you're a Tarzan fan, this is one worth checking out. Brix is quite an acrobat--he performed some moves that simply astonished me.
The sound is pretty scratchy in parts and some of the dialog is unintelligible...so keep your remote handy to pump up the volume from time to time.
If the other Tarzan Serials are almost as good, I want them in my DVD collection, too.
