Threesome leads to 2 pregnancies in trailer for new Zoey Deutch rom-com

As the Spice Girls once sang, tonight is the night when three become five.

Zoey Deutch, Jonah Hauer-King, and Ruby Cruz are in for a rude double surprise when they embark on a spontaneous threesome in the new trailer for the aptly titled romantic comedy The Threesome. They don’t just come away with a crazy story and awkward morning-after vibes, but two pregnancies.

“We can get through this, right?” Hauer-King’s Connor asks Deutch’s Olivia, the on-and-off fling for whom he’s clearly been pining. Maybe before they pulled a one-in-a-million ticket in the genetic lottery, resulting in both Olivia and stranger Jenny (Ruby Cruz) becoming mothers-to-be. “No, we are not doing this if there a side-piece baby mama,” Deutch curtly replies.

The first trailer for the film, which premiered at SXSW in March, plays up Connor and Olivia’s will-they-won’t-they dynamic, heavily implying that the “will they” is Connor’s domain, while Olivia holds down the “won’t they.”

“I want you to accept what you have with Olivia,” a character played by comic Jaboukie Young-White tells Connor. “You guys are friends! Friendish. Friend-adjacent.” But Connor might be onto something, as jealousy flickers in Olivia’s eyes when she sees him strike up a conversation with Jenny.

The film promises all the staples of a heartfelt rom-com: an awkward surprise family bash at Jenny’s, a live-wire love triangle that reaches new levels of entanglement, plenty of potential for sentimental conflict resolution, and chuckle-worthy one-liners like Young-White’s character’s, “So after years of perfection the pullout method has finally failed,” and Olivia’s regretful insinuation that Connor has “the world’s most potent freakin’ sperm.”

The official logline for The Threesome reads, “One fateful night, the stars appear to align for the unassuming Connor (Jonah Hauer-King) as his long-time crush, the irreverent Olivia (Zoey Deutch), steers them into a threesome with an alluring stranger named Jenny (Ruby Cruz). The unexpected encounter leads to romance and pregnancy, thrusting all three into a difficult and messy journey towards true accountability and adulthood.”

The film was directed by Irish-American filmmaker Chad Hartigan, a staple of the indie circuit for more than a decade with titles like Morris from America (Craig Robinson) and Little Fish (Olivia Cook, Jack O’Connell) under his belt. Ethan Ogilby, a longtime animation coordinator and editor on The Simpsons, wrote the script, his first to be developed into a feature film.
