My dad loved “Gunga Din,” a relic from 1939 about three British soldier buddies in 19th century India. They were played at their dashing-est by Cary Grant, Victor McLaglen and Douglas Fairbanks Jr. I was surprised by how much my dad adored this thing. Not that it was bad; it’s fun, still is. But my father, a former army infantry man, hated war movies. He never talked about his time overseas. As I learned growing up, this was not uncommon among veterans.
