Can this marriage be saved? Highly unlikely.

Love is on the line in the new trailer for the Scarlett Johansson and Adam Driver film “Marriage Story.” The Noah Baumbach-directed movie — which premiered at the Toronto International Film Festival in September — documents the anguish, tears and stony looks of a competitive married couple, Nicole and Charlie, whose relationship is unraveling. But the dissolution of their marriage is “not as simple as not being in love anymore,” says Johansson’s distraught Nicole.

With a custody battle for their young son (played by Azhy Robertson) looming — and the oblivious meddling of Nicole’s mother, who wants to remain Charlie’s BFF — the pair juggles courtroom appearances and meetings with lawyers, including Charlie’s, played by Alan Alda.

For better or worse, the couple is still tethered as one. “Eventually it’ll be the two of you having to figure this out . . . together,” advises Charlie’s attorney.

Meanwhile, Nicole’s lawyer, Nora Fanshaw (Laura Dern), asks her a simple, “How are you doing?” as Nicole rocks back and forth and looks down before hiding her face (and barely, her grief). “I realized I didn’t ever really come alive for myself; I was just feeding his aliveness,” a red-eyed Nicole says in another scene that underscores the very real possibility for Johansson, 34, to score an Oscar nod for the role.

The “Avengers” star’s wrought portrayal is a stark contrast to her real-life relationship with “Saturday Night Live” cast member and writer Colin Jost, who got engaged in May after a two-year relationship. (Johansson’s previous marriage to Romain Dauriac ended in divorce.)

Johansson seemed smitten during an appearance Thursday on “The Ellen DeGeneres Show,” telling the host that Jost nailed the proposal.

“He killed it,” she said. “He did, like, a whole James Bond situation.”

“He’s surprising. He’s got a lot behind that news desk he’s hiding,” she continued, alluding to his regular gig co-anchoring “Weekend Update” on “SNL” alongside Michael Che.

“It was very personal,” she added. “It was a very special moment and I think more than anything when someone tells you they want to share the rest of their life with you, it’s a lovely, special thing.”

“Marriage Story” will premiere in theaters on Nov. 6 and has a Dec. 6 release date on Netflix.
