James Stewart and Doris Day star in this 1956 Alfred Hitchcock Mystery/Thriller/Drama “The Man Who Knew Too Much,” in which Dr. Ben McKenna (James Stewart) is on vacation with his wife (Doris Day) and son in Morocco when a chance encounter with a stranger sets their trip, and their lives, on a drastically different course. The stranger, killed in front of the family in the marketplace, reveals an assassination plot to the Americans. The couple’s son is abducted in order to ensure the plot is kept secret, and suddenly the mother and father, with no help from the police, must figure out a way to get their child back.
Against this backdrop, Doris Day sings her famous faithful ballad, “Que Sera Sera,” which she at first refused to sing as “a forgettable children’s song.” The song not only went on to win an Academy Award but it also became the biggest hit of her recording career and her signature song. She went on the sing this same song in “Please Don’t Eat the Daisies” in 1960, and in “The Glass Bottom Boat” in 1966 as well as her theme song for all 124 episodes of her television series, “The Doris Day Show” starting in 1968.
