The Girl Who Knew Too Much (1969 film)

The Girl Who Knew Too Much is a 1969 American comedy film directed by Hy Averback and starring Adam West and Nancy Kwan. The plot revolves around a honeymooning couple, Johnny Cain (West), a bookstore owner with a penchant for detective novels, and his new wife, April (Kwan). While vacationing in Spain, they become embroiled in a mystery involving espionage, murder, and international intrigue after April witnesses a suspicious event.

The film is a lighthearted spoof of Alfred Hitchcock thrillers, particularly The Man Who Knew Too Much, playing on themes of mistaken identity, suspense, and the amateur sleuth. Johnny Cain, fueled by his detective novel knowledge, tries to solve the mystery, often comically misinterpreting clues and situations.

Despite its comedic intentions, the film was not a major critical or commercial success. It is perhaps best remembered for its association with Adam West, who had recently gained fame as Batman in the popular television series. The film represents an attempt to capitalize on his popularity and comedic timing, though it is generally considered a lesser work in his filmography. The film's humor relies heavily on slapstick and exaggerated situations, aiming for a broad audience.
