I'm trying to find the title of a live action 80s kids film. I saw it in the mid to late 80s, so I believe it was made before then. It was in color and had some blue screen work to achieve effects, as I remember. It had something to do with ghosts--maybe the house was haunted? There was some comedy to it. I think it was a kid's film because there were pre-teen kids in it. Definitely a B-film.
The only scene that I remember right now, features a teenage/young adult boy who I believe was a ghost. In this scene his feet detach and possibly begin dancing.
I don't remember any detached feet, but a commonly searched-for movie with kids in it is "Making Contact" (1985) aka "Joey." Most people remember the huge, mutant, man-eating cheeseburger though.
