Our Tony Award-winning guests –- scenic designer David Gallo (2006 for The Drowsy Chaperone), sound designer John Gromada, costume designer Susan Hilferty (2004 for Wicked) and lighting designer Peter Kaczorowski (2001 for the Producers) -- discuss how a design team enhances a production; when they are brought into the production and how they interact with one another as the show unfolds; their process in preparing for each show; their collaboration not only with each other but also with the director and the actors; the logistical challenges they face with each new show; how they got involved in theatre design and what training they did or didn't receive; advice they'd give to young designers; how they handle creative differences with other designers and the director; and where they find inspiration for their designs.
