A couple of years ago movie cells (bits of cut down 35mm film) were offered for sale here in the UK from The Lord of the Rings trilogy and Harry Potter films, all framed up with film photos, for about £70 - £100 each.
Now, hundreds of people bought them thinking they were sections of the actual film's original footage, from the sets. Of course, thanks to clever and mildly misleading wording in the adverts, they were nothing of the sort. They were just bits of old cinema reels that would have been binned when the local Vue had finished showing them.
Yesterday I bought sections from four movies, again mounted with photos, for £13. They included The Bourne Identity, Charlie and the Chocolate Factory (new version) and The Matrix.
All film will soon be digital, so they're my tip for the future if you want to start a cheap collection ;)
At just over three quid each, you can't lose much!
But I do feel sorry for the proud Lord of the Rings owners - not :p :
