Jasper in the Haunted House. Yeah, it's "of it's day," meaning racist, but the music and animation is great. If offended, accept my apologies and give it a pass.

It mystifies me why H-B never sold a Mr. & Mrs. J. Evil Scientist series. Maybe because they were a too obvious rip-off of the Chas. Addams New Yorker cartoons. Anyway, as a kid I liked them. Here they are with Snagglepuss, not exactly a Halloween icon, but kinda creepy for other reasons.

Betty Boop's Halloween Party. Surprisingly, kind of tame for Betty, but still fun.

Tim Burton's "Vincent." I've loved this since I first saw it, what, almost 30 years ago? Man, where does the time go?
