It seems to me she was. However, one sentence in the begining of the movie confused me totally.
Namely, when Glory is first entering Wayne's apartment. She says she is Frank's present to him. Wayne is confused and worried and asks what exactly Frank meant by that. And she replies that she is only going to be his friend for a week, and "nothing sexually isn't going to happen".
So, I guess that confused me. If she really was an escort girl, why did she then tell to Wayne she was only going to be his "friend"?
Since Glory's brother couldn't pay his debt it seems to me that she (by Frank's way of thinking) is obligated to him to do whatever he wants. She said that it only involved sex with the one guy from Detroit. I think, without knowing Wayne, that she probably thought it could become a sexual thing if that's what Wayne wanted. It didn't take long before she realized that Wayne was a nice guy who probably wouldn't take advantage of her.
Emperor: Tell me how he died. Captain Algren: I will tell you...how he lived.
It's unclear. She claimed not to be, but could have been lying. It's totally unrealistic that she wouldn't be. She had an expensive debt to pay and you don't pay it in the real world by taking bus rides or rubbing salve. And yet within the context of this silly little fairy-tale movie fantasy, it's possible she wasn't.
Aren't you gonna tell me to break a leg? Break 'em both.
OK, there is clearly more than one way to read this (innocent or whore), and I think maybe there are more than two ways to read it, too. Bear with me and consider a possible middle path: stupid about who she hangs with, but loyal to the extreme with her family. IF she was telling the truth about her brother's debt to a dangerous loan shark, then she was in a position to chose between 1) doing as she was ordered by this dangerous criminal and 2) letting her brother die at his hands. Since she said that she had originally introduced them (stupid), maybe she felt it was her fault her brother was in danger (loyal). Women who have sex with someone threatening them with death are not prostitutes, they are rape victims. What if it was her child's life she was trading for doing whatever was assigned -- would that be prostitution or rape? I read this movie this way: the Mad Dog character saw her as a victim of a very violent form of extortion. Worse than what was happening to the woman across the hall, who had a choice. He saw his partner defend the neighbor, and wanted to be that kind of brave man himself, but had to struggle to find it in himself. If she were trading sex for drugs or money or jewelry, then she would be a prostitute. But forced to chose between sex or death (whether hers or someone else's)? Offering the choice is a criminal act and she chose to be the victim herself rather than her brother (loyal). That makes her something of a martyr perhaps, but not a whore.
My take is a little different because I see her as being the cause of her brother's problem. She says, "...I put my brother together with Frank. Going to Frank is like taking heroin to cure an alcohol problem..."
This is not an innocent proposition. She made a bad choice to help her brother by hooking him up with a known criminal. She knew Frank "put money on the street." This is not innocent knowledge. It's not really even naive. She knows he is a loan shark, and she knows what happens when Frank does not get his money - plus enormous vigorish - he hurts people. She may not know he kills them, but that is not the point. She has a choice: let her brother take his lumps and lose his business without setting him up with a dangerous lunatic (what she should have done), or set him up with the loan shark when she has to know that it is almost impossible to ever pay these guys back because of the huge interest they charge.
In the case I am describing, she is neither a prostitute nor is she even close to being a rape victim. That's even more melodramatic than the film. She is a willing player who got in over her head (after getting her brother in over his head. Her brother is also a fool for agreeing with her to go to Frank, but that is another issue). What she is, is a girl who is willing to do whatever it takes to clear her brother's debt. She knows full well that it will probably include sex with people she doesn't know. There is no veil over this. She is someone who has gotten herself into a difficult situation, and she is willing to do what it takes to clear her brother and her own conscience. She is not a victim. Suppose that instead of a girl, it's a guy who does what she does. Say that, instead of sex it's violence that is required of the guy. Does that make him a victim of some sort of "rape?" Hardly. If he complies, then he is liable as an accomplice to illegal activities. The law would probably cut him a deal, but we're talking about moral ramifications here. He has become a criminal in order to save his brother. Noble but guilty.
Another message poster said something else well: She "reads" Wayne instantly and knows he's pretty straight. She knows he is the kind of guy who will feel "wrong" about any frank exchange of sexual favors for time off of a debt. So she lays off the sex angle. She pretends that it's just like she is a "girl Friday" or something. It sounds naive but she is just sparing Wayne the embarrassment he would feel by such a bald statement of facts. Frank isn't Marlowe. She isn't a virgin being thrown into the volcano, either. In order for her to be that, she would have had to have been kidnapped and forced into prostitution against her will. She would have had to be sacrificed to greed and lust. That is not the case.
A great film to watch that has some of these same questions in it is The Cooler. Maria Bello does something similar to what Uma Thurman does. Although Bello is playing a much more seasoned character than Thurman is, and she plays the game more willingly, she is no less or more guilty than Thurman's character. Everyone has a goal and everyone is willing to do what it takes to achieve that goal. Having sex is just one form of commerce. Are they both whores? Yeah, in a way they are. They agreed to become whores without actually stipulating that that is what they are. It's all just language. All I can say is, I wish I knew a guy who knew a guy...never mind.
Thanks for your comments here; you start with a point that I had overlooked -- that she was responsible for getting her brother together with the extortionist. That really does change her role from passively loyal sister/victim to one of the instigators and therefore liable for consequences from the beginning. I'll have to watch it again with that in mind. One things for sure, all three main characters are out of the ordinary as heroes, victims, and/or villians. Few of the standard cliches and assumptions apply.
Glory was working for Frank to pay off her brother's debt to him. Frank gave Wayne her for a week as a gift. Wayne didn't quite get why someone would give him a person and considering that Frank was dangerous he worried about it. Remember later when he sees the dead shooter in the garbage can?
