Two strangers form an intimate bond in “Together Together,” Nikole Beckwith’s comedy about a young loner who becomes the gestational surrogate for a single man in his 40s. A trailer for the Sundance pic sees Matt (Ed Helms, “The Office”) and Anna (Patti Harrison, “Shrill”) raising a toast to his sperm and her egg and uterus, but their connection runs deeper than the growing baby that unites them.

With “Together Together,” Beckwith wanted to explore “what such an intimate circumstance might do to the relationship between two strangers. The more I wrote, the more I realized I had an appetite for a story between a woman and a man that didn’t involve mutual attraction,” she explained in an interview with us. “There are a lot of different ways to be the object of someone’s affection, or to love someone.”

The spot shows Anna and Matt opening up about their lives to one another. “I’m not going to tell anybody,” Anna reveals. “I just don’t have anyone I really need to share the news with.” Asked why he is “doing this alone,” Matt shares, “Because I am alone. I am in this chapter of my life that feels like it should be over, but it’s not. It’s just on a loop. It’s weird to be perceived as hopeless in this moment when I’m actually incredibly hopeful.”

The pair’s burgeoning friendship is not without complications. Anna suggests they need “better boundaries” when Matt gets overly involved in her sex life, for example. Beckwith told us that “Together Together” challenges what the pair “think of love — or think of as love.”

As Matt observes, “Sometimes people just connect. It’s not about being attracted to one another.”

Beckwith made her feature debut with 2015 Saoirse Ronan-starrer “Stockholm, Pennsylvania.”

“Together Together” hits theaters April 23. It will be available on digital May 11.
