Atmospheric thriller / drama directed by René Clément, based on the novel "The Children Are Gone" by Arthur Cavanaugh, French produced and set in Paris with two major American stars, Faye Dunaway & Frank Langella plus the Canadian Barbara Parkins, it tells a story of Phillipe & Jill, an American couple with 2 kids, living in "the City of Light" for two years facing a marital crisis due to Phillipe's ultimately strange behavior & Jill's psychological problems. When their 8 years old daughter, Cathy & 4 years old son, Patrick are apparently kidnapped, Jill starts to uncover what's behind the mysteriously disappearance that might be related to her taciturn husband, Phillipe...
Slow paced & dreary, but effective on the thrills, "The Deadly Trap" (original title: "La Maison sous les arbres") keeps the viewer guessing, even if the end result was not that exciting and a bit too predictable. Some major editing errors, the low budget & a "made for TV" look to it, prevented the movie to became a cult classic of the genre like the moody & similar paced, "Don't Look Now" directed by Nicolas Roeg that was released about 2 years later, but it had its moments of skillful direction and nice shots of a gloomy Paris during winter time.
Faye Dunaway is very good in the lead role, from a devoted spouse & caring mother to a desperate woman fighting against her own psychological problems to remain lucid enough to find her children. Miss Dunaway's committed performance is a stand-out in the movie, elevating the final product to a "released to theaters" quality. A thirty-something Frank Langella, here some years before his iconic role in "Dracula", delivers one of his first experiences handling a quirky, odd, but somewhat darkly charming character, a kind of role he would be typecast for almost his entire career.
In short, "The Deadly Trap" isn't for everyone, but for fans of low-key psychological thrillers, the 70's & especially, the actress Faye Dunaway, it worth a watch.
