I watched this movie when I was a kid. I've been in love with it ever since, and today I find it even better for each time I view it.
This is a personal favorite, and I rate it higher than any other adventure movie I've seen. Steve Hawkes is the best and coolest Tarzan ever, Kitty Swan the best jungle queen, Marcello Giombini the best composer (how I wish I could come across the original soundtrack of this one) and Manuel Caño is my favorite Spanish director.
When I was a kid - I liked this one a whole lot more than other more classic Tarzan-movies, and my opinion today is the same (only stronger).
Whatever people might say about authorized or unauthorized Tarzans - Steve Hawkes will alway be the #1 Tarzan to me, and this one is without a doubt the very best of his two Tarzan-movies.
If anyone has the Spanish or Portuguese version and wants to sell it to me. Please drop me an e-mail (andreas@brus-online.com). I "only" have the Swedish, Greek and Norwegian prints.
