This marks the first meeting between characters Sam Evans (David Ford) and David Collins (David Henesy). Ford at first pulls back his fingers, preventing the younger actor from shaking his hand. Then Evans/Ford smiles, and the two shake hands. The expression on the young actor's face suggests genuine surprise, raising the question of whether the director told them to play the scene this way or else Ford played a prank on his fellow actor.
The closing credits voiceover promotes that evening's broadcast of Escape (1966): "In the rugged mountains of Austria, Peter Murphy and Eva Wainwright risk their lives to aid a priest in his flight for freedom on The Man Who Never Was, in color, tonight on ABC."
A DVD has this episode air date as June 29, 1966 on the disc's episode menu.
