Pharrell Williams is putting his time off from The Voice to good use: He produced and composed the music for the upcoming dramatic film Hidden Figures. Over the weekend, Pharrell sat in alongside the film's three leading ladies -- Taraji P. Henson, Octavia Spencer and Janelle Monáe -- for a Facebook Live Q&A at the Toronto International Film Festival. 

The film tells the lesser-known story of the three African-American women who played a large role in helping NASA launch John Glenn into orbit. The three women and Pharrell discussed the importance of telling such an inspiring story. "When I read it, I cried because I was emotionally attached to the women, but I was also upset, I was mad that I as an American didn't know about these American heroes," Monáe says.

The end of the Q&A sees footage from a concert that took place at the festival as well, in which an original song from the film's soundtrack debuted. Kim Burrell performed the lively and gospel-colored track "I See a Victory," complete with a gospel choir and appearance from Pharrell.

Prior to the performance, Pharrell wrapped the Q&A by saying, "I also want all the young girls, regardless to what color you are, I want you to see this film and recognize that not only can you do it, but it’s actually already been done."
