Casting On her role of Laurel, Patricia Wettig thought she was moving away from roles which had stereotyped her with "sensitive listener roles", although conceded that she "should probably resign myself to it". Kate Maberly secured the role after an unexpected call requesting her to attend an audition in New York with a day's notice while she was in England. She was taught to act blind and use a cane by Sue Martin, herself registered as legally blind. The cast plus extras exceeded 150 people. ==Production==
