1. Mikey (1992)
The gist: A sociopathic 9-year-old murders his foster parents in the first scene and is moved onto a new family. Yet again, his murderous intentions are soon revealed but because of his age, he always manages to avoid suspicion.
Why was it banned? The film's graphic depiction of a young killer was deemed inappropriate and potentially dangerous in the wake of the Jamie Bulger case in the UK in 1993 so was banned. Still to this day, it remains unavailable.
