Cheating is unfortunately a fact of life. And since movies likes to feed from real life, lots of movies include characters that either cheats or has cheated on their partners at one point in the story. This list doesn’t include details about the movies plots, but just features the parts about cheating.

Please note that “cheating” can be defined broadly, but here it is defined as engaging in any sort of sexual activity with someone other than one’s partner. I also mostly mention actors’ names, rather than characters names as it is easier to follow.

Here’s the first batch of movies with cheating characters:

1. Le Fate Ignoranti starring Margherita Buy and Stefano Accorsi

A man cheats on his wife (Margherita Buy) for 7 years and she finds out about it after he dies. Moreover, the mistress is a guy (Stefano Accorsi).

2. The Scarlet Letter starring Demi Moore, Gary Oldman and Robert Duvall

Cheating here wasn’t conscious. Demi Moore’s husband was presumed dead. Of course by this time she was already in love with, and had had sex with Rev. Arthur Dimmesdale (Gary Oldman).

3. Revenge starring Kevin Costner, Madeleine Stowe and Anthony Quinn

Madeleine Stowe’s character is married to the much older, rich and not so nice Anthony Quinn. Of course when an old friend of his shows up looking like the 35-year-old Kevin Costner (obviously played by Kevin Costner), the two hook up. However the consequences will not be pleasant if he finds out.

4. The English Patient starring Ralph Fiennes and Kristin Scott Thomas. Featuring Colin Firth

5. Derailed starring Clive Owen and Jennifer Aniston

Technically, the sexual activity started can’t be finished due to a violent criminal but that is a detail as the one of the characters - Clive Owen- was married and already in bed with his “conquest” (Jennifer Aniston) when a criminal invaded their hotel room.
