How big is your... Movie Collection?

I have 3 bookshelves occupied by 150-200 movies (somewhere in between, I didn't count).

70% DVDs

30% Blu-rays

And couple of funko toys along with one mask.

I probably have around 500 titles in various formats, but some of these are duplicated. I have Alien through to Alien Resurrection, and even Bladerunner on VHS format. So for movies like these I prefer to keep for posterity. Also the value of these may not be that much at present, but I have seen their value slowly creeping up, just as vinyl has. There are some movies in the past which I have had difficulty finding and upgraded format. The most difficult one I had trouble finding a good upgraded version was The Keep (1983), directed by Michael Mann. Eventually many movies get upgraded eventually, but there are still some out there that can be hard to find. Movies like Forbidden Planet took their time in getting an upgrade to DVD, but the conversion to Blu Ray was much quicker.

GAVIN - Oh, this is an increidbly fun topic! As a whole, I presently own approximately 435 movies on DVD which I keep catalogued  and ordered alphabetically. It is a pain in the posterior at times to keep my collection in order; but it is worth it! :)
