For decades, Marshall Mason and Lanford Wilson have been seminal figures in the theatre industry. Their artistic partnership spans nearly forty years and is recognized as being among the most enduring in the American Theatre. Their work together - from "Balm in Gilead" to the more recent "Book of Days" - stands as some of the most beloved in the American canon. In 2002, New York's Signature Theatre devoted its entire season to the plays of Lanford Wilson, including the New York City premiere of "Book of Days" which was directed by Mason. On the eve of that premiere, the SDCF was privileged to host Mason, Wilson, and long time collaborator and co-founder of Circle Repertory Company, Tanya Berezin in an in-depth One-on-One Conversation exploring their extraordinary careers, the craft of stage direction and the secrets behind their legendary director-writer collaboration
