Towards the end of the movie when the Graboid comes up through the floor of Walter Chang's store there is a scene when Val is on top of the cooler. He went up there to unplug it int he back so it would stop making noise. It's when Chang gets nudged into the cooler, bloodying his nose that, with a real keen eye, in a split second you can see that it is not Kevin Bacon a top the cooler but a stunt double dressed just like him and excpet for the nose, almost looks exactly like him!
