Robin Williams played Walter Finch in Christopher Nolan’s Insomnia.

Insomnia is a 2002 psychological crime thriller directed by Nolan and adapted from the 1997 Norwegian film of the same name. Williams portrays Finch, a crime novelist who becomes involved in a murder investigation in the Alaskan town of Nightmute.

Al Pacino stars as Los Angeles detective Will Dormer, who travels to Alaska with his partner Hap Eckhart to investigate the killing of a teenage girl. Hilary Swank plays local detective Ellie Burr. Williams’s performance was notably dramatic, contrasting with his better-known comedy roles.

Insomnia was Nolan’s third feature film and his first made for a major Hollywood studio. The film is often discussed alongside Memento because both explore guilt, memory and morally compromised investigators, although their stories and settings are different.
