So I started searching out the posters for some of my favorite films. Trouble is, some of the posters suck (Buckaroo Banzai) and some are expensive (Pillow Book), others nearly impossible to find (Manchurian Candidate). In some cases, I found alternate versions of the poster that I liked. But I now have lined one wall with movie posters and I'm quite happy with the ones I've ended up with.
This is what is across my wall - with the second poster directly over my monitor. (Most of them are 27x41, a couple are slightly smaller. Yes, it is a long wall.)
