Appeared in: Seasons 1-6
Standout Skit: FIVE MINUTES!
Where Is He Now?: Still in the biz, most recently writing and producing the Disney show, Austin & Ally

Kevin the Stage Manager, the backstage butt of All That's principle cast, eclipses half of the players that are actually featured in the opening credits. His uptightly wound micromanagement of the All That cast was always one of the most anticipated and endearing elements of the show, which starts in five minutes. And, as if his performances weren't alone enough to justify our ranking him so highly, keep in mind that Kopelow wrote for All That as well Kenan & Kel and the Good Burger movie.—Justin Charity
