Could anyone help me with the title of a creepy old 70s movie where these demon like creatures attacked a bus and its passengers. Its been driving me nuts!

If you find the answer please let me know - that very question is why I registered for this site!

Could it be Lemora: A Child's Tale of the Supernatural?
The whole movie is up on YouTube, check out Part 2 around the 7:35 mark.

Thanks so much Adolf! For some reason as a kid I thought the whole movie centered around that bus scene but then again I was 9 or 10! I've been looking for that movie for 20 years!

Cool, glad I could help.
I just happened to be watching it, and remembered reading your question when I saw that scene.
Funny coincidence.:D
