Since this was the sixth episode of Season 2 to be filmed, on June 24, 1965, but the final one to be broadcast (June 9, 1966), an introduction was filmed to present the episode as a flashback. Elizabeth Montgomery is still being portrayed as pregnant (even though she had given birth on October 5, 1965), and Alice Pearce is alive (she passed away on March 3, 1966). The interior set used for the Kravitz's home is also different, being the same as the Stone's family house on The Donna Reed Show (1958). Both series were filmed at the Columbia studio backlot.
Final black and white episode.
This is one of the few (if not only) episodes where Gladys Kravitz doesn't get freaked out by witnessing witchcraft.
