This week, we welcome a legend to the show. LeVar Burton has had a career that almost doesn't seem possible. He's been part of - in fact at the core of - a hat trick that continues to be unbelievably influential. Most actors would be thrilled to have had a fraction of his success. His career spans theater, film, and television, but above all there are three properties that define who he is and what he's give to all of us: Roots, Reading Rainbow, and Star Trek: The Next Generation.
