The great Luise Rainer, first winner of back to back Oscars, apparently wanted to play Maria badly. She didn’t know Hemingway and the studio had its eye on a young Ingrid Bergman, fresh off of her Casablanca triumph. David O., Selznick took Ingrid to meet Hemingway and he adored her. Luise just passed away but read about her regret.
In the new movie (Colin Firth as Perkins, Michael Fassbender as Tom Wolfe), Hemingway has a supporting role. Should be good!
