Here's a vintage public service announcement in which John Wayne promotes the American Cancer Society. Strangely, the spot has some factual errors. The Duke says he went for a check up after completing his 199th film...which may be accurate if you count every chapter in the old serials he made as a separate movie. The segment shows him in "North to Alaska", which was released in 1960. In fact, Wayne came down ill while filming "In Harm's Way" in 1964 and had a lung removed shortly thereafter which did save his life. The spot goes on to have him show a clip from the 1969 movie "True Grit" which he says was seven years after his diagnosis. In fact, the film came out only five years after his cancer surgery. Well, at least the spot was well meaning and did cause a spike in people getting cancer screenings.
