The Mondavi Center’s Focus on Film series continues Monday with a screening of the 1948 black-and-white British film noir classic “The Fallen Idol” in the Vanderhoef Studio Theatre at 7 p.m. Directed by Sir Carol Reed, who got an Oscar nomination for his work, with a screenplay by the well-traveled novelist (and undercover British intelligence agent) Graham Greene, based on Greene’s own short story, this morally ambiguous tale concerns an 8-year-old ambassador’s son, Phillipe (Bobby Henrey), left in the care of manservant Baines (Ralph Richardson) and his suspicious wife (Sonia Dresdel). The boy witnesses what he believes to be a murder, which the boy suspects might have been committed by a person he idolizes and wants to protect. Tickets are $10 general, $5 for students, available at www.mondaviarts.org or 530-754-2787. Mondavi Center executive director Don Roth will give a 6:30 p.m. pre-screening talk about the film.
