Filmmaker Rick McKay starred Elaine Stritch in his award-winning feature documentary, "Broadway: The Golden Age." Soon after he followed her through rehearsals with a camera and crew to create and produce the segment "Elaine Stritch: At Liberty" for EGG: the arts show" on PBS. Much of that footage, the only shot of the original show's rehearsals, appears in the HBO documentary, where McKay is credited. Stritch also appears in McKay's sequel to "Broadway: The Golden Age."
