You just didn’t see him in it. You heard him.
The actor, an accomplished musician, played the cello on the Rogue One score, the Los Angeles Times reports.
It’s a different kind of screen gig for the star, who’s better known for stints on TV shows like Shameless and New Girl, and for his memorable silverscreen roles in My Best Friend’s Wedding and last year’s Insidious: Chapter 3.
“I’m more of a journeyman player,” he tells the Times about his sideline job, musing that performing with an orchestra is “such a source of pride” for him.
In fact, it’s not the first time he’s performed on a film’s soundtrack. According to IMDB, the actor, 53, is credited with playing the cello on the scores for Mission: Impossible — Ghost Protocol and Star Trek Into Darkness.
The one thing that all his big-screen orchestral stints have in common: Michael Giacchino.
The Oscar-winning musician has composed the music for every film that Mulroney has played on, and, according to the Times, the two can trace their friendship back to 2005 when they worked on the comedy The Family Stone, which Mulroney headlined and which featured Giacchino’s music.
Of course, keen fans were already aware of Mulroney’s musical gifts. The actor, who reportedly started studying the cello as a fourth grader and had performed with his college orchestra, appears on the hit Amazon series Mozart in the Jungle. His role? A superstar cellist.
Mulroney, who performs and sings with his band Cranky George, once played on the Rosie O’Donnell Show — you can check out the clip below. And, during an interview earlier this year with the Today show, he chatted about his cello-playing skills, saying, in self-deprecating fashion, “If you can hear the 11th cellist in the back of the section, that’s me.”
We’re guessing Mulroney’s fans, and more than a few curious moviegoers, might be listening much more closely now to those cellos on the Rogue One soundtrack, if only to spy Star Wars‘ most unlikely star.
