Director Laughlin originally intended Strange Behavior to be the first installment in a trilogy of horror movies with the word "Strange" in the title. Laughlin's follow up, Strange Invaders, was the second film, however, the third film installment has yet to be made.
Michael Laughlin so enjoyed working with stars Dan Shor and Dey Young that he would cast them again as love interests for a cameo appearance in his next film, Strange Invaders. Several additional cast members from Strange Behavior would also join Laughlin on "Invaders."
The license plate on the character Waldo's red Thunderbird is noticeable for a split second when he gets behind the car to get the tire out of the mud. The back of the car says "Hollywood Nights" and has an Illinois tag, N2Z 264. Two years later Risky Business was released, and Tom Cruise's license plate was also an Illinois plate N2Z 264.
