Director Bob Clark shot this film back to back with Dead of Night as part of a two picture deal. Both films were shot in Florida and featured several of the same cast members.
Director Bob Clark (III) was planning to do a remake of "Children Shouldn't Play With Dead Things" in 2007. Tragically though, Clark died in an automobile accident before production plans could get underway.
When Orville is sitting on the couch with Alan, they move his arm and for a moment, you can see his normal "flesh colored" skin between the fake right ghoul hand and suit sleeve.
The 1990 reference book "Uranian Worlds: A Guide to Alternative Sexuality in Science Fiction, Fantasy, and Horror" by Eric Garber and Lyn Paleo lists "Children Shouldn't Play with Dead Things" as one of the first horror movies to show positive (though stereotyped) gay male characters who also have an important role in the story. With the help of these two gay men (actors Roy Engleman and Robert Philip) made-up as corpses, Alan plays a practical joke on the other characters that frightens them so badly that one wets his pants.
