Lesbian themes
I don't mean this to be derogatory and know that every person is different, but there were some pretty striking lesbian themes here, from the "new fish" moniker, to Elvira wanting Marie, to the line: "if you stay in here too long, you don't think of guys at all - you just get out of the habit." There is also the shower scene, Elvira calling Marie pretty, and Marie becoming strikingly more masculine in voice, tone and attitude after she submits to Elvira.
On a personal note, a lesbian I used to work with insisted on being called Harper, though that was not her name. I now think it was because of this film. Further a lesbian who lives in my building now holds her head, talks in a similar tone, and uses many of the mannerisms from this film. Again, I am not trying to stereotype and am not judging at all. I just want to say that I was frankly blown away by the similarities to lesbians I have known and what I saw in this movie. This movie is like Lesbianism 101, or something. That sounds awful, but it is not meant in a mean spirited way. Just my honest observation.
Lastly, perhaps it is her connection to this film that may have started rumors that Agnes Moorehead was a lesbian. I have heard those rumors as I am a big fan of hers, but I never had any idea what the basis for them was.
At least there will be plenty implied.
