British tennis pro Ray Milland suspects that his wealthy wife Grace Kelly is fooling around with handsome American Robert Cummings. Milland blackmails a disgraced former army comrade (Anthony Dawson) into murdering Kelly and making it look like the work of a burglar. But Milland’s carefully mapped-out scheme does not take into account the notion that Kelly might fight back and kill her assailant. When the police (represented by John Williams) investigate, Milland improvises quickly, subtly planting the suggestion that his wife has committed first-degree murder. He almost gets away with it; to tell you more would spoil the fun of the film’s final thirty minutes. Based on the popular mystery play by Federick Knott, Hitchcock perversely refused to throw in the standard in-your-face gimmickry of most stereoscopic films of the era. Source: Rialto Cerrito

Film starts at 7 pm Thursday, September 8. All seats are $8. Get to the Classics early as they are popular — or buy tickets in advance (see right column on the Rialto website). The Thursday evening Classics are very popular, so you may want to buy your ticket in advance at the box office or online. Getting to the theater early is always a good idea–for a choice of seating and to order freshly-made food and drinks.
