Somebody's gone and made a high-quality re-edit of the original Planet of the Apes as if it were a Twilight Zone episode. Yes, Virginia, there are video mash-ups. Somebody else got tired of waiting for the download, and put it on BitTorrent. Boing Boing has the link.
Legal? Don't ask me, I'm not a lawyer. Record companies have spent money on trying to keep music mash-ups ?? such as the "Grey Album" mix of Jay-Z's "Black Album" and The Beatles' "White Album" ?? offline. If you're interested, I'd watch this one fast before Fox Home Entertainment gets their lawyers on the case.
