Is there any good movies you can think of that are all based one a wife cheating on the husband or vice versa?

Little Children, is a recent one that comes to mind.
Faces by Cassavetes is kind of about cheating.

Indecent Proposal is an odd one.

I can't can't find much on "Faces or Indecent Proposal" on IMDB is Little Children a good one?

Umm...Unfaithful?

I Love You To Death

Derailed

shawshank redemption

Birth, in an odd way.

Trying to figure out a way to get away with it?

Oh, no one mentioned Disclosure. Ok, while not that good, it wouldn't be so bad being sexually harassed by Demi Moore... except for the married thing.

Thanks a lot, I will have to check into these movies.

Why?

Unfaithful is one of my fave movies of all time. Also, The Ice Storm dealt with cheating a little. And John Tucker Must Die which is better than I thought it would be.

A Perfect Murder.

L'Enfer deals with the perception of a wife's unfaithfulness. That's a great movie. Closer is another.

Seriously? If you must see a movie, don't see this pile of garbage, see Dial M For Murder, the original which was ten thousand times better.

Eyes wide shut?

The End of the Affair

Same Time Next Year - is a phenomenal film about adultery.

Seriously. I believe the question was about which movies, not their artistic merit. But, true, it's not exactly a work of art. It was also the first thing (for whatever reason) that popped into my head.

I am a big fan of Dial M for Murder and I would never argue that A Perfect Murder is as good or better. But a pile of garbage? Hardly.

And BTW, the alternate ending is much better. I think the story is that they weren't very pleased with the original ending so they decided on filming an alternate. By then, Paltrow was in England filming Sliding Doors (another good movie where infidelity plays a large role) so at great expense they packed up the set and hauled it all the way over there, filmed the new ending and then... didn't use it. They went with the original which was much more conventional and politically correct.

The Browning Version (1951)

popped into my mind immediately
