Watch: Jacob Elordi and Diego Calva Play Gay Lovers in Upcoming Movie 'On Swift Horses'

"Saltburn" star Jacob Elordi will be teaming – intimately – with "Babylon" star Diego Calva in Daniel Minahan's "On Swift Horses," due in theaters April 25.

The two play lovers in 1950s California, in the wake of the Korean war. The storyline concerns Muriel (Daisy Edgar-Jones), the wife of Lee (Will Poulter), as she and Lee move to San Diego and Muriel discovers a love of betting on horse races... as well as a connection with her new neighbor, Sandra (Sasha Calle).

Also forging new ties is Julius (Elordi), Lee's brother, a card sharp and former U.S. serviceman. Julius survived the war in Korea and now, working in a casino in Las Vegas, finds love with Henry (Calva) despite the homophobic climate of '50s America.

Elordi opened up to Vanity Fair about depicting the secretive affair, and enacting its sex scenes, in an interview last September.

"Though Julius has a strong sense of who he is, he feels a terror in expressing it, having experienced violence and betrayal all his life," Vanity Fair described Elordi's character.

In the film, the magazine recounted, Julius and Henry "develop a steamy sexual chemistry that includes several rich, emotional, and explicit love scenes."

Describing how Minahan – who also directed the queer-themed miniseries "Fellow Travelers" and "Halston" – approached the sex scenes, Elordi told Vanity Fair that "We had a week of intensive [prep] in the motel room, and Dan gave us a lot of freedom to run around and to play and to find that love within those four walls."

The new trailer features snippets showing the male lovers frolicking in their underwear as Calva's character declares, "We want something, we gotta take it." Moments later, he adds: "It's never been easy for people like us."
