A native of Cairo, Egypt, Massoud was three years old when his family emigrated to Markham, Ontario, Canada. He was in his late teens when he began earning TV guest spots, and his first few roles as a series regular came on shows such as The 99 (2011-2012) and Open Heart (2015). In 2018, he won a recurring role on the first season of Tom Clancy's Jack Ryan, and early the next year, he starred in the independent feature Run This Town.
Massoud rose to international fame in May of 2019 with the title role in Disney's blockbuster live-action remake of Aladdin. With Naomi Scott as Jasmine, their edition of the Oscar-winning song "A Whole New World" made it into the Top 40 of Billboard's Digital Song Sales chart, while the film's cast album topped the Billboard soundtracks chart. ~ Marcy Donelson, Rovi
