Galley Friend S.B. is nuts for this: A special DVD version of Return to House on a Haunted Hill, where you choose the outcomes as you watch.
Color me skeptical. I'm still scarred by the Clue movie and its three alternate ending gimmick--pay full price to watch the same movie again, but with 10 minutes of different footage at the end!
I was such a sucker. Damn you Professor Plumb!
