And after just five minutes of searching an auction site, CBBC Newsround found two DVD copies of The Two Towers being advertised.
They were on sale for around £20, even though whoever was selling them hadn't got them yet.
Their ad said they "expected" the quality of the movie to be "good - excellent" and added that they expected to have hundreds of copies.
But anyone buying them should be warned that the picture quality and sound is likely to be very bad, and they could get in trouble with the police.
