Thanks to Jeff Krulik, here are two video features from the National Trust for Historic Preservation featuring interviews with Ray Bradbury. In the first, he proclaims himself to be a "verbal architect". And in the second, he tells the story of the legendary "Brown Room" at Clifton's Cafeteria in downtown Los Angeles. Trust Modern recognizes this space as an unheralded landmark, important to the history of American literature.
