Did they or didn't they?

I think they did. Ann is a different woman when she visits her sister in the bar - much more relaxed and accepting of Cynthia and at the end, when she and Graham are sitting together and he is stroking her arm, they certainly looked as though they belonged together.

There is nothing in the film that would really be "evidence" that they did, however there is a logical conclusiveness that leads you there. If not then, in the particular scene referred to, it wasn't much later that they did. The question of morality raised by comparing anything that John & Cynthia did to what Graham and Ann may have done becomes academia. Their actions, as a reflection of their intentions, are comparable only in their great contrasts. As someone else pointed out (in part at least), these two (Graham & Ann) became different people because of the mutual stimulus that they provided for each other. In the beginning of the film they were both dysfunctional, but, I feel, that was due to their inability relate to the basically superficial and base natures of the people who were in their environment (Elizabeth included). They were both far too delicate, in the sense of refined, and inwardly honest and sensitive to function in such a banal atmosphere. Ann was right to reject Cynthia's attitude towards men as something distasteful, but there wasn't a man around her worthy of her tenderness and caring interest, so she tried to direct these attitudes into worthwhile things to care about e.g., the starving people etc. She appeared as a nut simply because there was no social sphere for her to be truly normal. Graham was basically in the same boat. He was crippled after he realized (earlier in his life) that all his externalized aggression was displaced frustration. As a result, he more or less castrated himself. He couldn't get it up, because he had killed out either superficial or base desire, and hadn't run into anyone to inspire the type of deeper (or higher) admiration and love that would motivate him. While John & Cynthia's relationship was symbiotic for the worse, Graham & Ann's took them both in an upward direction.
People who don't care for this film, I suppose tend to be more of the John & Cynthia types. This all reminds me of the Charlotte and Samantha dynamic in "Sex and the City".

I rather like that we don't quite know.

In the original script, in reply to John's interrogation, Ann says she didn't *beep* Graham. I prefer the film version where we don't know precisely if she did or not. She would have looked guilty about what she did whether or not his ******** ended up inside her ************ (random number of asterisks).

It's not about whether or not his ******** stayed hard for long enough for them to actually *beep*

The point is not whether he overcame his impotence on that particular occasion. The point is that it was his first attempt in years to actually connect directly with a sexual partner. He made a real attempt to connect with her and to please her in a sexual way. That is the important thing.

This is nicebat, my cyberpet.

I don't think it's stupid, scarymonster33. But as for me, personally I don't care if they did.. I really like that that was left to our imagination because it (Graham being physically "cured" by Ann at that moment) was just not the point. The point for me is that Ann had confronted him and touched him in a level no one seems to be able to (at least not since Elizabeth), she healed his spirit. Graham suggests that his lies kept him from connecting with anyone in a deeper level; when he tries to give up the lies it seems he also gives up the hope for connection.. until he is really ready for it. I think it's deliciously ironic that the pathological liar is the most honest character in the story.. Ann then forces him out of his shell, and he can finally be in a truthful, meaningful relationship.

I like the fact that we don't see what happened after Graham turned off the camera, because anything would be too final. And I don't think having sex at that time would lower them to Cynthia and John's level, not at all, because the way I see it it's not about morals.

I think it would be nice if they hadn't even tried, though; I like the idea of Ann curing him, but just not yet. If I had to form an opinion, I would say he just held her, and they kissed and talked..

I didn't care. The movie was that stupid.

Of course they did. The intimacy between them at the end didn't spring from out of the blue.

I know this is a super old topic but I want to point out to anyone reading this topic that

Some type of impotence where you can't get hard can be caused by depression and psychological issues.

The film explains that graham really hasn't had an erection with a woman for a long time.

When he turned off the camera when he was with Ann. I thought that it was because he experienced an erection for the first time since elizabeth and he felt like he didn't need the camera's anymore.

ann was the girl that cured his psychological or depression problems which led to him being able to get an erection.
