Kate Beckinsale stokes unlikely affair in The Only Living Boy in New York trailer

Kate Beckinsale causes a sultry stir for her adultering partner’s son after the 20-something college grad forcefully inserts himself into her life — an amusing affair that’s charmingly detailed with quirky flair in the new trailer for Marc Webb’s upcoming romantic comedy The Only Living Boy in New York.

The film centers on city dweller Thomas (Callum Turner), whose wealthy father (Pierce Brosnan) — unbeknownst to his wife (Cynthia Nixon) — engages in a secret affair with another woman, Johanna (Beckinsale). Her allure proves to be too much for Thomas, as he begins meeting with (and, at one point, kissing) her, adding another layer of complication atop the intricately woven familial dynamic — all while confiding in his eccentric neighbor (Jeff Bridges).

“People do things all the time without realizing,” Johanna tells Thomas as they share a drink. When the latter asks the former to pinpoint his intentions, Johanna responds, “You’re trying to make love to me,” before flirtatiously sipping her straw.

The clip closes as the Simon & Garfunkel song that inspired the movie’s title plays over a few words of wisdom spewed by Bridges’ character. “Life is as random as it is deliberate, funny as it is tragic. And yours is no exception,” he says.

Webb, who found success earlier this year as his Chris Evans/Jenny Slate drama Gifted earned $28.8 million (on a $7 million budget) at the worldwide box office, previously directed two films based on Marcel Comics characters: 2012’s The Amazing Spider-Man and its 2014 sequel, The Amazing Spider-Man 2.

The Only Living Boy in New York, which also stars Kiersey Clemons and Debi Mazar, opens Aug. 11 in theaters. Watch the film’s new trailer above.
