Peregrine Productions and Hawk Films

The production companies associated with this movie are called Peregrine Productions and Hawk Films, probably because their founder Stanley Kubrick had a thing for birds of prey.

And yes, Stanley Kubrick was a bit of a lone wolf—lone hawk?—when it came to having control over his movies. That's why he created his own production companies to make his movies. He used the Peregrine and Hawk labels on famous films like Dr. Strangelove, A Clockwork Orange, and Barry Lyndon.
