Mason Thames and McKenna Grace Star in Punk-Rock Comedy Nimrods

Actors Mason Thames and McKenna Grace are starring as romantic opposites in the punk-rock comedy Nimrods, hitting theaters on August 14, 2026. The film marks their second major onscreen collaboration following the October 2025 premiere of Regretting You, coming after the real-life couple publicly hard-launched their relationship earlier this year.

Collaborating on consecutive film projects is a rare occurrence in Hollywood, but Mason Thames and McKenna Grace have managed just that. While the punk-rock comedy opened in theaters on August 14, 2026, the production actually preceded their romance-drama venture.

From Green Day Road Trips to Screen Romance

The musical elements of the film run deep. Jakob Armstrong, son of Green Day frontman Billie Joe Armstrong, wrote the songs performed by the fictional band Analog Dogs. Both Thames and Grace contributed vocally to the movie’s soundtrack, with Grace also contributing her own original song.

“I mean, those kids are fantastic. They can do anything. And they’re the nicest kids, creative kids, very eager. They were up for whatever we wanted to do. I was so lucky that McKenna wanted to do it and she wanted to put her song in the movie. I just felt like it gave it some authenticity to it, and Mason with his singing, he rehearsed, he worked on those songs, which were written by Billie Joe’s son, by the way. Yeah, Jakob wrote those songs for the Analog Dogs.”

A Relationship Built Across Film Sets

The working relationship between Thames and Grace extends well into a real-life romance that has been documented publicly over the past two years. According to Thames, the pair first crossed paths in an Uber on the way to a movie theater. We just clicked immediately, he noted of their initial meeting, noting they have spent all their time together since.

Their professional partnership began to align with their personal lives in August 2024, when they were confirmed to star in the film adaptation of Colleen Hoover’s best-selling novel. Filming for Deadline began in March 2025, paving the way for a high-profile press tour and red-carpet appearances that culminated in an October 2025 premiere.

Behind the Scenes of Back-to-Back Productions

Reflecting on the unusual production schedule, Thames expressed excitement over releasing the punk-rock project after holding it as a private experience for months. Working consecutively on two entirely different genres—a punk road-trip comedy and an emotional family drama—offered unique professional dynamics for both actors.

“So we did Green Day first. Green Day movie first, and then we did Regretting You right after. But it was just so wild. The coincidence of two back-to-back is awesome and we love it.”

Grace’s dedication on set left a strong impression on her co-star. During press appearances, Thames praised her rigorous work ethic, noting that watching her commitment motivated him to push harder in his own performances.

“She is such a star, and she’s such a warrior. I’ve never met somebody with a work ethic like hers. She pushes herself every day harder and harder, and she’s so incredibly talented. So just watching that, it really motivates me.”

Public Milestones and Future Prospects

After months of shared TikTok appearances, NBA date nights, and red-carpet events, the couple officially hard-launched their relationship in February 2026 when Thames shared an Instagram carousel featuring Grace kissing his cheek in front of the Eiffel Tower. They subsequently attended the Academy Awards together as a couple in March 2026.
