20 Things You Probably Missed From Scream 2
14. Mickey's Camcorder Is A HUGE Clue
Mickey of course turns out to be one of the film's two killers, which shouldn't be that surprising in retrospect considering that he's shown obsessively taking his camcorder with him everywhere he goes.
It's revealed later on that Ghostface has been recording footage of the killings, and given the image quality and manoeuvrability required of the camera, it's pretty safe to assume the killer was using a compact camcorder like Mickey's. Precisely Mickey's, in fact.
Though it's not exactly a secret that Mickey loves to film around campus, few fans have actually put two and two together.
