Russell Collins was a Hitchcock favorite, appearing in no fewer than nine episodes of "Alfred Hitchcock Presents" and one episode of The Alfred Hitchcock Hour (1962).
Early in the show, in the sales office, the calendar on the wall shows that February has 29 days in it, making the year a "leap year," which would also be a U.S. presidential election year, such as 1956, 1960, 1964, etc. (Nevertheless, this episode aired in March 1959.)
