If you are looking for context or a "cheat sheet" on the movie starring Diane Lane and Richard Gere, here are the key takeaways:
: The film focuses heavily on guilt, obsession, and the arbitrary nature of infidelity . It suggests that affairs often happen even in "good" marriages, rather than just dysfunctional ones.
: The original theatrical release has an ambiguous ending where Edward considers turning himself in for his actions. However, an alternate ending available on DVD shows him actually going to the police station to confess.
