When Microsoft co-founder Bill Gates, the richest man in the United States, came to the Sundance Film Festival here this week, it wasn't movies on his mind, it was education -- your kids' education.
A new documentary, "Waiting For Superman," by director Davis Guggenheim ("An Inconvenient Truth") looks at what Gates and Guggenheim say is a U.S. public school system in shambles.
"The quality of our educational system is what made America great. Now it's not as good as it was, and it needs to be a lot better," Gates told Reuters after the film's premiere on Friday.
"Many of these high schools are terrible, and this film, 'Waiting for Superman' by Davis Guggenheim, which I have a very minor part in, tells this story in a brilliant way," he said.
