Tilda Swinton Says Her Pedro Almodóvar Film with Julianne Moore Is About 'Adult Things' and 'Friendship' (Exclusive)

"We've actually met a couple of times over the years. And we've always wanted to hang out more and more," Swinton tells PEOPLE of Moore

Tilda Swinton is overjoyed to be working with Oscar-winning filmmaker Pedro Almodóvar and costar Julianne Moore.

At the premiere of the new movie Problemista in New York City on Tuesday, Swinton, 63, gushed about her first time acting alongside May December star Moore, 63, in the their upcoming film, The Room Next Door.

"We've actually met a couple of times over the years. And we've always wanted to hang out more and more," Swinton tells PEOPLE of getting to know the Academy Award-winning actress. "And the best way of hanging out with someone you like is to work with them. And now we're together and we're loving it."

"We're in Madrid and we've been there for two months, and we're going to be there until the summer and we're really happy to be together," Swinton adds.

Spanish filmmaker Almodóvar's production company El Deseo confirmed the movie's title and Swinton and Moore's involvement when it re-shared a post on Instagram about the film in January. The movie will mark 74-year-old Almodóvar's first foray into a feature-length, English-language movie after he debuted an English-language short film, Strange Way of Life, at the 2023 Cannes Film Festival.

"Oh, you can expect a really delicate Pedro Almodóvar film that's really about adults facing tricky adult things about friendship," Swinton tells PEOPLE of The Room Next Door. "I mean, it's really about good, good friends, and what good friends do for each other."

The upcoming film will mark Swinton's second time working with Pedro Almodóvar after their 2020 short film The Human Voice, the filmmaker's first English language short. Moore also confirmed her involvement in The Room Next Door in January when she shared a photo of herself, Swinton and Alomodóvar reviewing the project's script to Instagram.

Swinton starred in Problemista amid an array of roles in 2023, including parts in Asteroid City, The Killer and two short films. The new movie from former Saturday Night Live writer Julio Torres, who wrote, produced and stars in the film, follows Torres as an El Salvadoran immigrant in New York City who obtains a job with an eccentric artist (Swinton) in hopes of retaining his work visa and realize his dreams of designing toys.

"When he sent me this script, I was just so thrilled to know that he knew who I was, and thought that I might want to come and play with him," Swinton tells PEOPLE of working with Torres on Problemista. "And I love the film so much."

Problemista releases in theaters March 22.
