18 Movie Stalkers You Should Not F*ck With

Wouldn't we all love Ryan Guzman to be stalking us? Not if he's threatening your teaching career and the safety of your family, like he does in The Boy Next Door. Noah (Guzman) appears to be a good mentor for Claire's (Jennifer Lopez) son, but when he gets her drunk one night and seduces her, things get real. He then refuses to leave her alone, joining her class as a student and pitting her son against his philandering father (John Corbett).
