I was watching some behind the scenes interviews about Seinfeld's pilot. The network told David and Seinfeld that they liked the show but wanted a female co-star. David was absolutely against it. For what reason, I don't recall. However, David acquiesced with the intent to write Elaine as a male character.
This approach is interesting for a couple of reasons:
1. Elaine is unique in sitcoms because as a female she is written with flaws. She isn't just needy, but bitchy, righteous, shallow, vain, dense (extremely rare for a female character to not be the smartest), and her part of her comedy is a result of bad things happening to her or her poor decisions, not her being inhumanly witty and acerbic ALL THE DAMN TIME like most "funny" female characters.
2. Did David and Seinfeld realize the inaccurate portrayal of women on TV and in movies? Was insisting on writing her character essentially as male somehow saying, "Hey look, in all the shows on TV every female character, though sometimes not very interesting, is entirely smart, capable, competent, pretty, and successful. Women aren't like that. They're much like men. They do dumb things. Smart things. Fail. Succeed. We will write a character with the warts and all that reflect the American female." Or perhaps I'm too optimistic in how red pill David and Seinfeld are.
