Sorry for the little info I have on this... It was an early 80's movie (thinking 83-85 maybe). A group of kids is running from something or maybe trying to get somewhere. They draw a doorknob on a brick wall. When nothing happens one of them says" try knocking" and a door appears. Any ideas?

LOL! Oh bugger.. I know that movie but I can't remember either! :D

Try asking at Retro Junk | Hey I remember that (http://www.retrojunk.com) they'll be able to answer the question.

There is a part in BeetleJuice when they draw a door on a brick wall and they try knocking and it opens. Maybe?

Beetlejuice and they consult the manual for the newly departed I think, to get the info to go and visit their counseler. Hence the reason for the chaulk door.
