The movie, Adam's Rib came out in 1949. It was about a married couple, both lawyers, facing off against each other in court, about whether a woman, as opposed to a man, could invoke the "unwritten law" that a passionate shooting of an adulterous spouse was not murder. It had a further theme that the wife won the case, and was considering running against her husband for judge. My understanding was that women professionals were rare (at least in the United States) going into the 1950s.
Having been born in the U.S. during the 1950s, I remember the idea of women's equality being "discussed" in the 1950s and 1960s, but not gaining wide acceptance until the 1970s (or, at earliest, the very late 1960s). Kramer vs. Kramer, a movie about a father (rather than mother) getting custody of the couple's young boy, was the "mirror image" of Adam's Rib, was released in 1979.
So was the ethos of Adam's Rib 20 to 30 years ahead of its time? How was the movie viewed when it was first released?
