“Unfaithful” could easily be seen as a gender reversal on “Fatal Attraction” as this time the wife cheats on her husband. Plus, both movies were directed by Adrian Lynne, and “Fatal Attraction” inadvertently created a formula of psychotic attraction which lasted for many years to where we got “Unlawful Entry,” “Single White Female” and “Swimfan” among other movies. “Unfaithful,” however, is not held captive to this formula, and it becomes not so much a thriller as it is a drama with profound conflict. It doesn’t end with an audience pleasing conclusion as it does with ambiguity over how to resolve a situation bound by inescapable moral complications.

The movie stars Diane Lane as Connie Summer, a happily married wife to Edward Summer (Richard Gere) and mother to Charlie (Erik Per Sullivan). On one massively windy day in downtown New York, she accidentally runs into French bookseller Paul Martel (Oliver Martinez) who invites her to his apartment to take care of her painfully scraped knees. This ends up with her meeting Paul again several times before they embark on a passionately sexual relationship which contrasts with the loving but average marriage she has with Edward. But it all ends up becoming an addiction she can’t quite tear herself away from, and the destruction of her marriage becomes more and more imminent as a result.

Unlike the average formulaic thriller which clearly delineates good and bad to where the wicked get the punishment they deserve, “Unfaithful” never lets the viewer off easy. It poses questions to the audience which they might not want to answer, and they linger long after the movie is over. The film was adapted from Claude Chabrol’s 1968 French film “The Unfaithful Wife,” and it doesn’t feel like much was changed in the translation. Connie’s affair ends up creating a ripple effect which severely affects those people she loves the most in life.

Edward is no idiot as he suspects something is up, and the stress and confusion we see on his face gets worse and worse. What he discovers leads him to commit an act of which he never felt capable, and we are left to wonder if he should be punished or forgiven. Lynne never leaves us with any easy answers in “Unfaithful,” and this makes this film all the more compelling.

Lane already had a long and successful acting career before this movie came along, but this is the role which brought her the audience she long deserved, and there is no forgetting her after this. The role of Connie Summer is a great one for any actress, and Lane more than rises to the challenge. While she is cheating on her beloved husband, she still makes her character very sympathetic and brilliantly portrays her conflicting emotions. The scene where she is heading home on the subway after her first sexual tryst with Paul is a marvel of film acting as her face is a stunning portrait of regret and excitement. Seeing Lane experiencing various emotions makes for an unforgettable acting moment which deserves much study for future generations of actors.

Gere, considered by People Magazine to be one of the sexiest men alive, is every bit her equal as Edward. It’s almost weird to see him in this kind of role because we have previously seen him play characters who either cheat on their spouse or run off with someone else’s wife. Here, he plays a loving husband who hasn’t done anything wrong, so this situation provides much confusion for him as well as a pain he hoped never to experience.

As for Oliver Martinez, it’s easy to see why anyone could easily fall for him. He exudes sexiness both in appearance and the way he speaks. But more importantly, he never makes Paul Martel a character with overtly evil intentions. This is not a man who can be easily described as a villain, but one who follows through on his passions regardless of the consequences they may bring about. When he comes face to face with those he has hurt, Paul never flaunts his ego or berates them. The way he sees it, he has done nothing wrong and never intended to wound anyone so deeply.

If “Unfaithful” were directed by anyone else, it would have made the wife more sympathetic and the husband a one-dimensional bastard to where you’d want the wife to cheat on him. But Lynne is far more interested in providing a fascinating portrait of a relationship which is not bad off, but instead one which turns out to be more susceptible to temptation than at first glance. The good guys and bad guys are never easily told apart in this story. There is a darkness in all the characters here, and it’s a darkness they don’t see until it’s much too late.

There was much talk after “Fatal Attraction” of how the original ending was changed to something more audience pleasing, but turning Glenn Close’s character from a wronged person into a psychotic menace who met a deadly end never sat well with many people. It’s as if Lynne has been paying a price for this ending ever since, and “Unfaithful” almost serves as a make up for him taking the easy way out back in 1987. Whatever the case, “Unfaithful” is a compelling drama which allows its actors to shine in ways we have not seen previously. Lane is a revelation here, and her performance, like this movie, is hard to shake.

Of course, “Unfaithful” still leaves the audience with one other burning question much like the one posed in “Fatal Attraction:” Why cheat on your spouse when they are played by Anne Archer or Richard Gere? Well, we may never know.
