According to reviewer weerdo1482,an animal trainer is wrestling with the leopard.I believe that it's actually stuntman and (later)stunt coordinator George Robotham.He's best know in later years as the (current )husband of German actress and beauty Karin Dor.
Anyhow,I'm just rather curious as to wether he's also doing the swinging through the trees,in a wide number of scenes,or if it's Denny Miller swinging around.
Any help on this issue will be genuinely appreciated.
