Michael Richards as Martin Beck in Problem Child

Martin Beck, a.k.a. The Bowtie Killer, is Junior’s inspiration and mentor—a kindred spirit of sorts. Junior doesn’t even flinch when Beck turns up at his home and tells him he might not make it to his eighth birthday. It takes a psychopath to know one. Luckily for Junior, his dad cares enough, in the end, to go rescue him after Beck kidnaps him and puts him on the right path—sort of.
