Until Dean Jagger depicted the title character in the 1940 film Brigham Young, he was a little-known actor. He went on to star in White Christmas and Twelve O'Clock High (1949), for which he won an Academy Award for Best Supporting Actor.
Jagger joined the Church in his late 60s after marrying Etta Mae Norton, who was a Mormon. He appeared in nearly 100 films and was awarded a star on the Hollywood Walk of Fame in 1960.
