One Hour Photo is a 2002 American psychological thriller film[2][3] written and directed by Mark Romanek and starring Robin Williams, Connie Nielsen, Michael Vartan, Gary Cole and Eriq La Salle.

The film stars Williams as a photo technician who develops an unhealthy obsession with a family to whom he has long provided services.

[4][5] One Hour Photo received positive reviews from film critics, including praise for Williams' against-type performance, for which he earned the Saturn Award for Best Actor.

Armed with a knife and a camera, Sy forces the lovers to pose naked in sexual positions while he takes pictures.

The exit door trips an alarm, and Van Der Zee pursues Sy while Outerbridge finds Will and Maya physically unharmed but emotionally traumatized.

However, early in the process, Romanek was allegedly pressured by the studio to hire a "real composer", and Reznor was dropped from the production.

In one of the voice-over pieces, Sy can be heard saying, "They actually believe that any idiot that attends a two-day seminar can master the art of making beautiful prints in less than an hour.

Williams prepared for the role by training for two and a half days in a Southern California photo development lab.

[9] In an interview, Romanek said that he was inspired to create the movie by films from the 1970s about "lonely men", notably Taxi Driver (1976).

Yet the consistent delicacy and emotional clarity of Williams' acting in One Hour Photo makes the picture impossible to dismiss.
