[quote]Also, had Audrey still been receiving million dollar offers back in 1967 do you really think she would announce retirement? She could easily have had productions move dates around her pregnancies/depressions whatnot
This ... person ... is very invested in the idea that Audrey Hepburn faced backlash, that her career was over by 1967, that the only possible reason she stopped making movies was either because there was no demand or because she wasn't getting offers she liked.
Hepburn's lack of an Oscar nom for MFL was indeed considered a bit of a slap, but that "backlash" was over by the time of the awards themselves. Hepburn, in fact, was asked to present the best actor award (which everyone knew was almost a guaranteed win for Harrison), and she got a huge ovation when Bob Hope announced her. She was delighted when Harrison one, and Harrison made a point of holding onto her, so she stood there with him while he made his speech, and he also said he felt he should really divide it in half and give part to her (his way of saying "fuck you" to the Academy for not nominating her). Then he did something gracious himself (which he wasn't known for), and thanked "two fair ladies" before leaving with Audrey.
When Andrews was interviewed after her own win, she acknowledged that she would not have been able to do "Mary Poppins" if she had been signed for "Fair Lady," since "fair Lady" began shooting in the middle of the "Poppins" shoot. As it was, the beginning of the Sound of Music shoot became tricky when she was needed for Poppins retakes. (In fact, when Andrews won her Golden Globe for Poppins, she thanked the "man who made it all possible," Jack Warner, to huge laughs.) The "backlash" was officially over, and Hepburn's next film, "How to Steal a Million," was a big hit both critically and financially. Then came "Two for the Road," which was a critical hit. By that point, "Wait Until Dark" was written for her (she was offered the stage version, too, but didn't want to do that, just the film. Lee Remick did the play, knowing that she wouldn't get the film which was already committed to Audrey).
Sorry to burst your bubble, but if you bothered to read any of the many books or articles about Hepburn, you'd know she didn't stop acting in 1967 for any reason other than wanting to get away from film making for an extended period - and then, she got pregnant and had a newborn (along her her older son, Sean) to take care of.
