Misery? Great book and a great movie, but a better book IMO. Basically an authors number one fan saves him after he wrecks his car in a snow storm. But, being that she's a lunatic, she soon turns on him in a bad way. It's a good movie, if you haven't seen it, or it's been a while, it's definitely worth a watch again. I promise.
Tough one for me because I was very young when I saw the original Mummy with Karloff and it scared the crap out of me, gave me nightmares.
OTOH, Michael was the Boogie Man that kept coming back, he was freaking relentless. Forgive me Karloff, I'll never travel to Egypt but Halloween is less than five months away and I have to sharpen my knitting needles.
