"I am a theater rat," announced Kevin Spacey last night to a Tribeca Film Festival crowd gathered for a festival panel centered on the making of "Now: In The Wings On A World Stage," a documentary chronicling the first trans-Atlantic theater troupe, the Bridge Project Company, as they took "Richard III" around the world. After viewing the film, two things became very clear: 1) "World Stage" is no understatement, as the 20 British and American actors and director Sam Mendes traveled and performed in Greece, Italy, Beijing, Australia, New York, and beyond, and 2) that being a "theater rat" involves grueling work, vivid adventures, pain, passion, humor, and verve. Spacey, director Jeremy Whelehan, and company members Jeremy Bobb, Hadyn Dwynne and Gemma Jones sat down following the film and talked about traveling the world, "House of Cards," and why theater will always trump film for Spacey.
