Well, we all know that HALLOWEEN (1978) is the quintessential Halloween movie, but there are other films that deal with the holiday we should mention.
One of them is LADY IN WHITE (1988).
A wonderfully nostalgic ghost story that takes place, for the most part, in 1962, Lady in White tells the story of young Frankie Scarletti and his harrowing adventure on Halloween night. He's been locked in the school cloakroom, and what he encounters there...well, I don't want to give away too much.
I looked forward to the DVD, bought it, and watched the thing once. Hardly anything to do with Halloween, but lots of murders, lot of wink-wink, nudge-nudge to films like Pet Sematary, and that's pretty much it. BORING.
At least, Halloween III has something to do with the Celtic origins of the holiday, so it's a good choice for Halloween viewing. Did you know that some of The Exorcist takes place on Halloween night? And Arsenic and Old Lace also takes place during the Halloween season.
Though Carpenter's Halloween is supposedly the "ultimate" Halloween movie, I find the atmosphere to be sorely lacking. Outside of a few pumpkins, one or two jack o'lanterns and some dead leaves skittering about here and there, I see very little about Halloween in this movie. All the leaves on the trees are green, for example.
