A woman of Laura's looks + age CELIBATE in 1960 London? LMAO!!
OK, I know it was to make the point that she was singularly dedicated and focused on work, and giving up so much more than her male colleagues, yadda-yadda, but REALLY now... jazzy, prosperous, post-war London (or NYC or Paris, or anywhere), everyone was shagging everyone! So to portray her living this solitary sexless life, is just HIGH-larious... kind of like several other plot points... hmmmm...
Bloody Hell, luckily it's all just Hollyweird fiction, 'cause otherwise I'd be MORALLY OBLIGATED to travel back in time, to before I was born, AND GIVE HER A VIGOROUS ROGERING! Smoking ciggies not even a problem... picture Demi/Laura bent over, in her stockings, garters, and high-heels, elbows on the window sill, head outdoors, ashes falling in the courtyard, her "girls" swinging up and back in unison, LOL! (That scene wound up on the cutting room floor, I'm guessing... ;^)
