Here's the criteria: I want a clip from any particularly popular movie or TV show which features somebody at the some other person's door, with the other person saying (possibly?) "What?", "Who are you?", and possibly shutting the door in their face.

I have an idea that would require splicing in footage through that open door - but, while I can easily find the footage to splice in (I never had a doubt about that), I'm having a hard time thinking up where to get the relevant footage of the door, see.

So, yeah. Ideas?
