Attempting to categorise classic Hollywood stars as feminist or anti-feminists is basically a futile exercise.
In the first place, the term "feminist" or "feminism" didn't come into wide usage until the late 1960s, when the "2nd wave" was in full swing. In fact, when the term did become popular, many of our most influential leading ladies rejected the term. When talk show host Dick Cavett asked Bette Davis if she would mind if he light her cigarette for her she responded, "Oh, no, I'm not woman's lib." During Katharine Hepburn's interview with Cavett, he asked her if she was inspired to support the women's movement, to which she replied in the negative: "No, because we did that, you know, a very very long time ago."
Secondly, the level of an actress's feminist tendencies is not inherently indicative of her strength of character. Nor does it in any way quantify or qualify her abilities as a performer. For example, some may call Joan Crawford a feminist because she worked so hard to earn a fantabulous career, while others can only see her as a complete witch-with-a-capital-B. At the opposite end of the spectrum other stars, like Judy Garland, may seem like nothing more than vulnerable victims of the studio system, and yet their inner strength of character still bedazzles audiences decades later.
So, what is the point of trying to label actresses as either feminist or not?
