Favorite movie on cheating (relationships)?
 

My all time favorite movie on cheating has to be Closer. What other kinds of movies are like that or follow that theme? it can range from unfaithful, to high fidelity (another great movie)

Road Trip.

Don't tend to watch them due to a previous issue with this subject.

Way to ruin Closer.

Also the one I thought of. :)

Love Stinks, more about relationships in general, but they do date other people to piss each other off. I think it is the funniest relationship movie around.

I haven't seen Closer but Fatal Attraction immediately jumps to mind.

The Graduate

I'll second Lunatikk's choice.

Unfaithful
The Seven Year Itch
American Beauty

It swirves over into a different genre, but Match Point is a great film revolving around cheating.

Fight Club ;)
Sideways

A good movie that guys can enjoy..

Scenes From a Marriage

Intolerable Cruelty

Closer is the only movie I can think of where cheating is very unsexy and undesirable. Usually there's the titillation factor that comes into play.

Fatal Attraction is definitely the worst case scenario.

The 1984 movie "Love Letters" starring Jamie Lee Curtis and James Keach is the most accurate, heartbreaking depiction of an affair I've ever seen (from someone who has been in her character's situation more than once).

Fatal Attraction definately has such an impact on me, I can't watch it again.

Closer is my favorite movie regarding the subject.

We Don't Live Here Anymore comes in a close second.

"Derailed" is a great great great movie.

I forgot to mention In the Mood for Love.

After The Wedding

The Last Kiss

I guess because I saw it recently and can relate to it a little moreso than other films I've seen on the topic.

The Kevin Kline Double-Feature:

The Ice Storm
Consenting Adults

I like Closer but for some reason Unfaithful draws me in every time.

If you want to see some good cheating sex, then

Thief of Hearts is your movie.
