Professor Marcus (Alec Guinness) is the leader of a crime ring planning a heist. His confederates, blowhard Major Courtney (Cecil Parker), suave Louis (Herbert Lom), chubby Harry (Peter Sellers) and muscleman One-Round (Danny Green), dodge their landlady's constant interruptions. The hoods hit upon the idea to use her in the daring daylight robbery, but she discovers the truth...it may be the end of her!
Love this film. Alec Guinness gives an acting masterclass supported by a wonderful cast, and one of my all time favourite endings to a film. Long live Mrs Wilberforce!
