River's Edge
River's Edge is a 1986 American independent crime film directed by Tim Hunter, written by Neal Jimenez, and starring Crispin Glover, Keanu Reeves, Ione Skye, Daniel Roebuck, and Dennis Hopper.
It follows a group of teenagers in a Northern California town who are forced to deal with their friend's murder of his girlfriend, and the subsequent disposal of her body.
Screenwriter Jimenez partially based the film's script on the 1981 murder of Marcy Renee Conrad in Milpitas, California.
Shot in Los Angeles in 1986, the film premiered that year at the Toronto International Film Festival before being purchased for distribution by Island Pictures, who gave the film a theatrical release in the United States in May 1987.
Several critics praised the film's performances, and its subject matter resulted in it being classified by several critics as a contemporary-day horror film.
It was awarded Best Picture at the 1986 Independent Spirit Awards.

In a 2015 retrospective, "Salon" deemed it "the darkest teen film of all time.
