Bruce W. Smith and Ralph Farquhar cast Zachary Quinto and Billy Porter in “The Proud Family” reboot because they thought their voices worked well together. They didn’t know both were Pittsburghers and Carnegie Mellon University graduates.
Quinto and Porter provide the voices for a gay couple, Barry and Randall Leibowitz-Jenkins, in "The Proud Family: Louder and Prouder." When Smith and Farquhar realized that Quinto and Porter had known each other for years, it seemed like a sign from the universe that this project was on the right track.
"Those are the things that let you know it's the right time for this show because things are falling into place in a very serendipitous way," Smith told the Post-Gazette.
