In turns enchanting, brooding and cowed like a cornered animal, he [Isaac] plays the perfect James Stewart character in this Hitchcockian homage.
 The narrative is very well-balanced and restrained from the hyperactive traps of modern cinematic storytelling.
 Not so much a morality play as a tale of amorality, this psychological drama makes for a movie that is moody and deeply satisfying.
-Excerpts from IMDB reviews
The principal relationship in this film (referred to as “a reto reworking of film noir” by one viewer) is between two men (one of them married; the other drawn to his wife). Chester MacFarland (Viggo Mortensen) is a rich American touring Greece w/ his younger wife, Colette, (Kirsten Dunst). The man who is intrigued by them is young tour guide, Rydal Keener (Oscar Issac), who is also American (yet able to blend in w/ the locals due to his language skills). Chester reminds Rydal of his father, who recently passed away, and w/ whom he had a difficult relationship. At first, Rydal thinks he has the upper hand; soon he realizes that he may have taken on too much by offering the couple his help. Who is the true con-man here?
Adapted by the director, Hossein Amini (who is British-Iranian), from a novel by Patricia Highsmith (The The Talented Mr. Ripley; Strangers on a Train), this film is an atmospheric, well-acted thriller set in beautiful locations (Athens, Crete, and Istanbul) w/ great (’60s) costumes. Amini knows how to heighten the tension as the film goes on. This film is tightly edited, which adds to its effectiveness. The music fits very well w/ the action, too. You can watch it on Netflix.
