This was a John Huston directed movie with a who’s who of Hollywood : Marilyn Monroe, Clark Gable, Eli Wallach, Montgomery Clift, Thelma Ritter. The screenplay was by Arthur Miller who was at the time married to Monroe. At the time (1961) it was NOT a commercial success but has come into it’s own recently.
The producers wanted two Magnum photographers to shoot the stills so out of NYC came Henri Cartier Bresson and Inge Morath. The drove together out from NY to Reno, NV. This road trip is the basis of the book “The Road to Reno” by Morath. It is interesting that Morath and Miller eventually married.
