I've got this projector screen set up in my room (5 foot by 7 foot screen ) and I was thinking about putting posters up to give the room a cinema feel. But where should I go to get them cheap?

If you don't know anywhere, we can just let this descend into a thread of which (3?) posters you would put in your room.

what do u call cheap?
i have some and i got them from my local cinema.
i think i paid a pound for my last one

I bought a few from moviepostersdirect.co.uk. I don't think they're the cheapest, but they're pretty quick and they've got a good variety.

Respect for the projector screen though! I've always wanted a cinema room in my house.
