Suggestion of bisexuality? (SPOILERS)

I don't think bisexuality of any kind of hinted in this movie. That artist woman was there to the show the fickle nature of Amy's character that she goes on doing different but never really feeling immerse and full. Which is why she envied Rick and went back to studying med. when that didn't work, as she said she flunked her exams, her character moved on to new things as being an artist and moving to Paris. This artist was only there to show how empty and confused she really was. I didn't think there was any hint of a sexual nature. She mentioned that woman was here friend. So I just left it there.

Kirk Douglas acknowledges the film's homosexual subtext in his autobiography, The Ragman's Son.

According to Douglas, all of the actors (including Lauren Bacall and Doris Day) understood the subtext.

Definitely.
Add the following to the other quotes that suggest bisexuality or gay.
After the party and the scene between Amy and the artist lady and their little "moment" they had standing close together hand touching arm and looking at eachother

Amy and Rick have the fight.

Rick says "you're so confused yourself you've got me confused"

Amy responds. "I'm not confused any longer. I'm fed up with you. I'm sick of you trying to touch me..."

I think that suggests she realizes she is gay and knows what she wants. And maybe that's what she's been looking for all along in her life. She's gone from one project to another, never completing things, pretty much looking for love. And she finally finds it with a woman.
That's my take on it. It's interesting How we can all see the same film but interpret things differently.
Anyway I love this film. I think Kirk Douglas is fabulous, I love the story. I'm a music person myself, use to play piano, always had an ear for music so I appreciate this kind of story. love movies about musicians and artists, they always Grab me.

BS. She has the sexuality of a vampire. She seeks out people with real talent and leeches off of them, ruins them. Her sexual proclivities would be purely incidental.

Yeah, I noticed this too.

I first started thinking as to Amy trying-out for the pink team when she nonchalantly talked about going-off to Paris with some woman (an artist no less- which was another old-fashioned "code-word" for gay) she just met. And then I saw the post-party scene with the "artist" (a stunner) and it really struck home that Amy had found her next "project" as to "passion" and it wasn't just this woman's art.

Whether Amy is a closeted homosexual discovering her true self or she's a crazy conniving bee-otch who bounces from one "experiment" to the next I think is left-up to each individual viewer. However, the film heavily hints that either way she's entering a relationship with that artist.

It's not really surprising that this 1950 film was able to sneak references to bisexuality/homosexuality pass the censors because other films did as well. They just had to be subtle about it. Although references to lesbianism, as in this film, were rarer than to male homosexuality.

Sometimes they weren't all that subtle- see Stephen Boyd's portrayal of "Masala" in William Wyler's "Ben Hur." The doe-eyed looks Boyd's character gives Chuck Heston's "Judah" are less than subtle. Or Edward Dymtrick's "Crossfire" which is supposedly about anti-Semitic bigotry, but comes across as more about homophobia because its source novel was about the murder of a man for being gay. However, the Code didn't allow any overt references to homosexuality so the victim in "Crossfire" became a Jewish guy who also happens to pick-up drunken men in bars so they can "talk."
