Here are our picks for some of September’s most promising new titles. (Note: Streaming services occasionally change schedules without giving notice.

Eve Hewson plays Amelia, a middle-class gal about to marry into a rich and famous clan, led by the pot-smoking patriarch Tag Winbury (Liev Schreiber) and his hyper-judgmental wife, Greer (Nicole Kidman), a best-selling author. When a member of the wedding party turns up dead on the beach, the police interrogate the guests, gradually piecing together a story that involves deceit and old grudges. Directed by the veteran art-house filmmaker Susanne Bier (who also directed the Netflix hit “Bird Box”), “The Perfect Couple” is less about the crime than it is about the delusions and pretensions it exposes.‘Rebel Ridge’Starts streaming: Sept. 6After making a foray into literary adaptation with “Hold the Dark” (2018), the writer-director Jeremy Saulnier gets back to the lean pulp thrills of his critically acclaimed “Blue Ruin” and “Green Room” with his latest movie. “Rebel Ridge” features an original Saulnier script about a military veteran named Terry Richmond (Aaron Pierre), who has a run in with some swaggering rural southern cops. The officers seize his money, then conspire to punish him further when Terry pushes back. AnnaSophia Robb plays a court clerk who helps Terry dig into the rot spilling downward from the corrupt local police chief (Don Johnson). Although the film deals with the serious contemporary social issue of civil asset forfeiture, in spirit it has a lot in common with the likes of “Walking Tall,” “First Blood” and other old-school action pictures in which one man takes on a whole town.‘Monsters: The Lyle and Erik Menendez Story’Starts streaming: Sept. 19In 2022, the producer Ryan Murphy and his frequent creative partner Ian Brennan delivered one of Netflix’s most-watched mini-series with the Emmy-nominated “Dahmer — Monster: The Jeffrey Dahmer Story,” a dramatization of the life and crimes of a notorious serial killer. The next season of their ripped-from-yesterday’s-headlines anthology series pluralizes the title — from “Monster” to “Monsters” — and covers the brothers Lyle (Nicholas Alexander Chavez) and Erik (Cooper Koch) Menendez, who murdered their parents, José (Javier Bardem) and Kitty (Chloë Sevigny), in 1989. The cast also includes Ari Graynor as Leslie Abramson, the attorney who attempted to paint the brothers in court as the victims of an abusive father, and Nathan Lane as Dominick Dunne, the Vanity Fair columnist whose reporting on the trial was filled with gossipy detail about the Menendezes’ upscale Los Angeles lives.‘Twilight of the Gods’ Season 1Starts streaming: Sept. 19Zack Snyder’s latest Netflix project is this adult-oriented animated series, set in the lusty, violent milieu of Norse mythology. When Thor (Pilou Asbaek) disrupts a mortal wedding and instigates a devastating massacre, the bride and groom — the warrior Sigrid (Sylvia Hoeks) and a king named Leif (Stuart Martin) — set out on a mission of revenge. Soon, they and their soldiers find themselves caught up in ancient rivalries, involving the likes of Loki (Paterson Joseph) and Odin (John Noble). Snyder and his “Twilight of the Gods” fellow creators, Eric Carrasco and Jay Oliva, don’t spare the gore or the nudity as they tell a tale that stretches from the underworld to the land of giants, with a Hans Zimmer score to help set a grand, epic tone.‘Nobody Wants This’ Season 1Starts streaming: Sept. 26Based loosely on the personal experiences of its creator, Erin Foster, the romantic comedy “Nobody Wants This” stars Kristen Bell as Joanne, a popular podcaster who riffs on sex and dating alongside her sister Morgan (Justine Lupe). Then Joanne meets Noah (Adam Brody), a sweet and funny rabbi who recently broke up with his longtime girlfriend and has since been fending off a steady stream of his congregants’ daughters and nieces. The show is partly about how an agnostic exhibitionist and an emotionally reserved, deeply religious guy overcome their differences and form bonds, with each other and with their respective sets of friends and family. But it’s also about two middle-aged people searching for some grounding and direction in their hectic lives.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
