Elaine Stritch appears in director Rick McKay's documentary Broadway: The Golden Age, by the Legends Who Were There (2002) and was reunited with McKay at the suggestion of PBS' EGG: the Arts Show creator Jeff Folmsbee, which led to "At Liberty" being filmed for television, with this the only footage of that legendary rehearsal process.

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."
