Alan Shapiro, Morgan Creek Prods. and Warner Bros, were sued by a Los Angeles family alleging that the film
La ragazza della porta accanto (1993) libeled their daughter. Plaintiffs noted, among other things, that the film's central female character, a psychotic killer with an unrequited crush on the man who rents her parents' guest house, shared their daughter's first name Darian (which was changed to Adrian in later film releases). Shapiro, who promoted the film as inspired by a real-life experience, lived in the plaintiffs' guest house in 1982. The suit was eventually settled.
