The Greatest Showman's Benj Pasek and Justin Paul had spoken before about a "sweet song" they had written for Aladdin and Princess Jasmine, but it seems that it didn't make the final cut.
"We shot a lot of stuff that didn't make it. There was a new duet that me and Naomi [Scott] sang together," Massoud told Digital Spy.
"I had to learn how to juggle and I had to learn to play the oud, which is that classical Middle Eastern guitar or string instrument. In the end, it's Naomi that plays it in the film, so a lot of things can change."
Still, the new skills he learned for the movie didn't go to waste as Massoud added that people still ask him to juggle.
Aladdin also challenged Massoud to stay in character when Will Smith improvised during filming.
"We had one scene together which is called the jam scene now that we improvised. Guy [Ritchie] was an absolute champion in trusting us with that moment and allowing us to take over and see what happened," he recalled.
"It's a beautiful moment that I'll remember forever."
Talking about his role in the movie, Will Smith has previously said that he was "feeling sexy about myself" as the Genie.
Aladdin is released in UK cinemas on May 22 and US cinemas on May 24.
