The story of "Gremlins" was conceived by Chris Columbus. As Columbus explained, his inspiration came from his loft, when at night "what sounded like a platoon of mice would come out and to hear them skittering around in the blackness was really creepy". He then wrote the original screenplay as a spec script to show potential employers that he had writing abilities. The story was not actually intended to be filmed until Steven Spielberg took an interest in turning it into a film. As Spielberg explained, "It's one of the most original things I've come across in many years, which is why I bought it."
