*All the animals were hurt during the making of this film. 

Genuinely deranged slice of the “animals on the attack” subgenre that flourished in the late 70s/80s. 

The animals in Frankfurt zoo get dosed with prodigious amounts of PCP and go on a kill rampage. Too many WTF moments to fully list, but does include:

Polar bear in children’s ballet class. 
Cheetah chasing a VW beetle. 
Rats vs flamethrowers. 
Elephants crashing a 747. 

Highly recommended. Obviously.
