Steven Spielberg: "I am optimistic, I have always been that way."
"I am not a brooding guy, I don't brood; I am optimistic; I have always been that way. But I also know how to embrace tragedy. I know how to embrace darkness."
In a very nice interview, director Steven Spielberg talks with CBS News' Lesley Stahl about the influence of his mother, Leah, his optimism and about making films both light and dark.
