Watch Supernova's Emotional Trailer with Stanley Tucci and Colin Firth

With a global debut today at the San Sebastian International Film Academy, Supernova has released its first trailer. The film, which is a British drama revolving around two long-term gay partners, was written and directed by Harry Macqueen. It comprises his second feature as director and stars Stanley Tucci and Colin Firth.

The plot shows Tusker, played by Tucci, and Sam, played by Firth, taking a long road trip in their RV in the wake of Tusker's early-onset dementia diagnosis. They see family, friends, sights, and celebrate Tusker's birthday in the trailer. But the film is an emotional one as the pair have to confront their feelings and love for one another in the context of the illness.

Reviews have said the pair, neither of whom are publicly known to be queer, "shine" and "dazzle" as a couple. "Their easy chemistry," which was built on a two-decade friendship. "is a strong selling point," according to The Hollywood Reporter. The publication went on to call the project a "tasteful tearjerker" that could use a "few more explosive fireworks."

It was apparently Tucci who suggested that Firth play opposite him in the project, as previously revealed. That said, the pair was unsure about who should play which character.

"it was interesting because it took us a while to work out who would play which character," Macqueen told Screendaily. "At a table read, they each read both parts for me, which is amazing and doesn't happen very often."

"They both really fell in love with both characters," he continued. "And it took them and me quite a few weeks to sort of figure out what the best configuration was going to be. We absolutely made the right decision. But I also think they both had a bit of sadness to be not playing the other character."

Wow, versatile actors. Who would have imagined?
