Film producer Graham King confirmed that Marc Martel recorded vocals for the film in a Rolling Stone article:"Most singing scenes in the movie rely on either vocal stems from Queen master tapes or new recordings by Marc Martel, a Canadian Christian rock singer whose voice is practically identical to the late frontman's. 'Literally, you could close your eyes and it's Freddie,' says King. 'And that's a very tough thing to do.'"And in an interview to FilmJournal International he revealed more details about Martel's involvement in the making of the film:"Rami sings a little bit in the film, there's a lot of Freddie Mercury obviously, and a lot of Marc Martel. He sent a video to Brian May and Roger Taylor and he sounds exactly like Freddie Mercury. We knew that we had someone we could use for parts that maybe Rami couldn't do and obviously Freddie didn't do. So we were in Abbey Road recording studio for maybe two and a half months with Marc and with Rami, recording bits and pieces that we knew we needed.
