Saw on TV in the seventies: someone murders people each in a different way. One scene he made some kind of vegetable mixture and dribbled from ceiling onto a lamp on a nightstand and on to the victim. Sent down insects (spiders?) to poison (or eat?)victim.

There’s a scene in the Bond film “You Only Live Twice” that’s very similar to what you’re describing. https://youtu.be/FNrjej-gYZM
