A pilot for Mr. Tutt, a series produced by Desilu and based on a Saturday Evening Post story about a curmudgeonly lawyer, was not made into a series, but it was broadcast on Colgate Theatre (September 10, 1958). The Variety reviewer considered Brennan excellent in the part, even though the script for the pilot was subpar. Brennan's subsequent career on television might have been quite different if this role had made the same indelible impression as Amos McCoy, a part that made it difficult for audiences to accept Brennan as a sophisticated character in a series that did not have rural aspect to it.
