At first, "L'Invité Du Mardi" seems to be just another clichéd "The Postman Always Rings Twice" copy. But then it hits its stride in an exceptionally well-crafted middle section that takes some very unexpected twists & turns and makes great use of "real time"; ultimately, this film is just as much an incisive marriage study as it is a riveting chamber thriller. Very well-acted by the three leads. *** out of 4.
