I stayed away from the Anthony Minghella Ripley, having previously seen Rene Clement's version, Plein Soleil, starring Alain Delon--at the height of his considerable beauty--as Ripley, as well as having read Patricia Highsmith's Ripley novels years before. I did so because I understood that Minghella's script portrayed Ripley, played by Matt Damon, as overtly gay, whereas he is not in the novel. This seemed to me to be a huge misinterpretation of the character. If it exists at all, Ripley's homosexual orientation needs to be subliminal and unacknowledged. Highsmith herself in an interview stated that she didn't believe Ripley to be gay, instead she saw him as an opportunist--sexual and otherwise--happy to do whatever would bring advantage to him. In the Clement film, Delon beds Marie Laforet's Marge, lucky girl. (I've never cared to know what Matt Damon and Gwyneth Paltrow's Marge get up to.) Delon's Ripley is more interested in Maurice Ronet's Greenleaf wardrobe--that is, his lifestyle--than he is in his dick.
If I remember correctly, Pauline Kael discerned a sexual tension between Delon and Ronet, with the emphasis on between.
