The Trouble I've Seen
Martha Gellhorn was a novelist and foreign correspondent and journalist who covered the Spanish Civil War, Vietnam, World War II, and numerous other conflicts around the world. Martha and Ernest connected at a Key West bar in 1936, beginning a "tumultuous" romance. The pair were married for five years and For Whom the Bell Tolls was reportedly inspired by Gellhorn.
I'm not certain about the Owen-Kidman casting, but I am quite interested in this backstory of this acclaimed pair.
