The show was supposed to be color from the beginning, but sponsor Procter & Gamble, who regularly sponsored NBC's Sunday night half hour programs between Disneyland (1954) and Bonanza (1959) insists that the show would be in black and white.

As originally broadcast in 1965, the opening credits showed Chuck Conners being cashiered from the Army. In the process, his sword was broken and the pieces were thrown to the ground making a peculiar sound.
