Two questions

I saw "A Double Life" for the first time yesterday, enjoyed it more than I had expected, and have two questions for those more aware of its production history/

(1) The Ruth Gordon / Garson Kanin script was wonderful, especially the characterization of the couple . That got me wondering if they based them, partly of otherwise, on anyone they knew in the New York theater scene. There was something more real and immediate to their complex relationship that you don't usually see in Hollywood films of that period.

(2) The film's title seemed to have a double meaning. It could have been referring to how Tony loses himself within the characters he plays on stage, and it could also refer to his habit of picking up lose women for sex. If the latter is the more "correct" reading, I'm wondering if the film's script, as some stage, made his sexual behavior more clear. We see him early in the film meeting two women on the street, with whom he had some sort of relationship in the past. When he picks up the Shelly Winters character he clearly is not doing something new to him. So where there any changes in the script, or in editing the film?

The best part of the film was seeing Shelly Winters get killed. I can add this film to "Night of the Hunter" and "Lolita". She somehow gets on my nerves (less so in this film), and I'm always glad when she gets it.
