Is there a connection to Ernest Hemingway?
I ask this because Elizabeth Hadley Richardson (http://en.wikipedia.org/wiki/Elizabeth_Hadley_Richardson) was Hemingway's first wife . The female lead in this film is Elizabeth Hadley. Other than the name, there appears to be no further resemblance between the two women. Is it a curious coincidence?
When it comes to films, I don't believe in coincidence most of the time. They heavily research names and such just to be sure that they don't accidentally align a character with someone. My bet is that someone is a big Hemingway fan.
ETA: It is also interesting that of Hemingway's four wives, the one possibly named in the film is the one who is grandmother to both Margaux and Mariel Hemingway; both are (or were) actresses.
