Saw this film back in the 60's, when I was around 8/9 years old, and I was very impressed by the amazing filming of two jaguars hunting together and tackling crocodile,anteater and anaconda. Back then such footage was very rare and this film became a top favourite of mine- 10/10 . But, as an adult I now believe that it must surely have been staged and, as jaguars are such hard to film creatures, then perhaps more than two animals were filmed and lots of smart cutting and editing used. But, still... 7/10...
