Rampage is a 1963 American adventure film starring Robert Mitchum, Elsa Martinelli and Jack Hawkins.
Abbot intends to bring along his longtime young mistress, Ana, an Italian waif whom he has kept as a ward since she was 14.
Arriving at a destination where they are to recruit an army of beaters to drive the cats into nets, they find the locals uncooperative.
While Stanton organizes a plan to drive it out an exit hole on the far end, Abbot seeks to prove himself still man enough to hang onto Ana and rashly goes in with a torch.
Abbot boils over and releases the big cat from its cage in a freight car, leaving Stanton trapped inside with it.
