Unsold pilot: Wrote the teleplay for a pilot for a proposed CBS adventure series called "Calhoun" (aka "Calhoun: County Agent") starring Jackie Cooper and Barbara Stanwyck. NOTE: Miller co-wrote a book about its development called "Only You, Dick Daring! (or How to Write One Television Script and Make $50,000,000)" that became a best-seller.
He was the author of a famous book about President Harry Truman, first published in 1972, a year after Truman's death. However, some sections of the book were claimed by others to be fabrications, and certain remarks attributed to Truman were said to have been invented by Miller, something he denied.
