You may recall that a few months ago, host George Smart interviewed Kyle Bergman, director of the Architecture and Design Film Festival in New York City.  Today’s special bonus edition features George and the stars, producers, and creators of the latest architecture documentaries, recorded in New York at the Architecture and Design Film Festival late last year.   Many Americans think the last World's Fair was in New York in 1964 but they've been going on around the world ever since - just without America's participation. George’s first guest is Mina Chow, producer and star of Face of a Nation: What Happened to the World’s Fair, and later on, he talks with Bruce Inglis, director of Photography for the documentary Glenn Morcutt: A Spirit of Place.
