I wanted to start a post on people who have seen a movie in the past but don't know the name of the movie.Hopefully we can get some answers on long lost movies that someone here might have seen.

One movie I have been looking for...It takes place I think in the late 70's in a shopping mall.There is one of those big plexiglass containers full of money that a fan in the bottom blows everywhere.It is a contest or something where someone can enter to win the money in this thing.Anyways two thiefs dig a tunnel or something under the mall,cut a small hole in the bottom of this box and use a vacuum cleaner to suck out the money.What's this movie?

you do have an answer to this one don't you or will we all be plagued with restless sleep and imdb'ed out looking for it lol
