Kevin Bacon was originally set to make a cameo as a crossover with The Following (2013), also produced by Kevin Williamson. However, the producers decided that "one set of our psychos is enough for one universe," and scrapped the idea. When asked about future crossover episodes, Williamson shrugged and stated: "I'm sure Joe Carroll - James Purefoy in The Following (2013) - did a fair amount of stalking in his younger years."
