Very minor spoilers ahead...
There's a scene in this where Sonny bashes out a door panel with an axe, as the occupant of the room is trying to escape. All through the scene I'm thinking this is ripping off 'The Shining' but then I realised this film was made 10 years earlier than Kubrick's and when the panel finally gives way Sonny pops his head through the panel and shouts - in his best Brit schoolboy accent - "Hello!"
Funny how when we see a door being bashed in with an axe and then a face poking through it we always seem to think of Kubrick's film isn't it?
