Anne Marie Martin, who played Wendy in Prom Night (1980), has an uncredited cameo as Karen's friend Darcy. She came on to help out when reshoots were being done.
Dick Warlock's (The Shape) son Billy appears as one of Ben Tramer's friends.
Creator Backlash: John Carpenter feels that this was an inferior script and says that the only thing that got him through the writing process was a six-pack of Budweiser every morning.
Dawson Casting: This time it's a little more pronounced than its predecessor, as the still 17/18 year old Laurie is played by a now 23 year old Jamie Lee Curtis (thanks to this Immediate Sequel being filmed three years later).
