Elephant Fury (1956)

German big game hunter brings elephants back from Africa safely through enemy lines, but they go on a stampede in Berlin. Filming began during WWII in Germany, but production was stopped because story showed Third Reich police and military having problems coping with an elephant stampede; after the War, it got completed by its originator, and exported to the US with English dubbed, while removing all references to its 1940s German origins!
