"Welles wrote, produced, and narrated this show, and his work was considered a prime contribution to the war effort," wrote the Museum of Broadcasting.

At the end of Welles's 13-episode contract (November 9, 1942–February 1, 1943), Ceiling Unlimited was hosted by a variety of personalities including Charles Boyer, Joe E.
