Meet Geoffrey Canada, the man behind the movie title, Waiting For "Superman."

"One of the saddest days of my life was when my mother told me Superman did not exist," he says in the film. "She thought I was crying because it's like, 'Santa Claus is not real.' [But] I was crying because there was no one coming with enough power to save us."

Geoffrey is also a man with big dreams, an educator who wants to fix public schools in this country. He founded Harlem Children's Zone, a school in the poorest, worst-performing district in New York. There, children attend class from 8 a.m. to 4 p.m., from early August through to the following July. For the past two years, the program has seen nine out of 10 of its children go to college.

"A real American hero, you are," Oprah tells Geoffrey. "You have actually become Superman for education."
