Colbert said, "We’ve restored the original dome and chandelier, and added a few hidden doors for fun" [1]. The tour specifically highlighted three secret doors used within the theater [1].

An unnamed CBS senior producer said the Ed Sullivan Theater is a New York landmark and that the team is proud to preserve its legacy while giving it a modern twist [2]. The production sought to showcase the historic restoration as a tribute to the venue's long history of broadcasting [1, 2].

The tour was filmed in mid-May to coincide with the show's closing ceremonies. A CNN media analyst said Colbert’s final week will be a celebration of the show’s history [3].

The decision to highlight the architectural restoration of the Ed Sullivan Theater serves as a symbolic closing chapter for the program. By focusing on the venue's status as a New York landmark, the production emphasizes the show's place within a larger lineage of American broadcasting, framing the series finale as both a personal conclusion for Colbert and a preservation of the theater's historical legacy.
