I don’t know....she tried to enlist in the WACs and then in the WAVES. Neither would allow her because she was too tall. She kept trying, even after she was rejected.
I think she probably was a strong patriot, but movies and those who make them being what they are, they try to put as negative a spin on such sentiments as possible - as I remember it, they did show a bit about how she came from a staunch conservative Republican family with the obligatory snarky comments about such roots, and her husband was portrayed as being beset and hounded by those evil people in whatever government agency he was working for who were trying to expose possible communist influence in its operations - as shown it seemed her patriotism was downplayed and had been muted perhaps because of dissatisfaction with her family and sympathy for the travails of her husband - but politics aside “Julie ad Julia” was good picture especially in showing how she developed her cooking interests and career, and some of the unintentionally funny situations she got herself into on the way.....
