Lifechanger: Davis Guggenheim Tackles U.S. Public Schools

"Extra's" Mario Lopez met with producer Davis Guggenheim in this week's Lifechanger feature sponsored by Walgreens -- talking about Guggenheim's powerful new documentary, "Waiting for Superman," which examines the U.S. public education system.

Guggenheim explained, "Why can't we give every kid in America a great education? That's what this movie is about. It's about all of us recommitting to making our schools great."

The Oscar-winning producer of Al Gore's environmental opus, "An Inconvenient Truth," said he was "so inspired by the families" in "Superman," which follows five students going through the terribly flawed public school system, each with their own dreams and aspirations.

"There's a little girl named Daisy in East L.A. who wants to be a doctor, and Anthony in Washington D.C., who just wants to make his grandmother proud. We have to fight for these kids."

One of the film's biggest fans is President Obama. "The exciting thing is that we took the five kids from the movie to the Oval Office."

So who is "Superman"? "You're going to have to go see the movie to find out, but it's not who you expect."

"Waiting for Superman" is in theaters now.
