Trivia: When Herman and Grandpa are locked in the counterfeiting room, Herman says "Call Batman." He was obviously referring to the Detective Comics series, where Batman first appeared in issue 27, in May, 1939. The Batman series starring Adam West debuted January 12, 1966.
Suggested correction: This movie was released in June 1966 so depending how long before that the filming took place, it may have been from the new Batman show (at that time).
That would be a possibility, as The Munsters debuted on television Sept. 24, 1964. Munsters Go Home appeared June 6, 1966. The Batman series starring Adam West debuted on television January 12, 1966. So given the dates, you would be correct, and given off-screen possibilities, I stand corrected, as I didn't have the correct dates at the time.
Trivia: Steve McQueen received his only Oscar nomination for his performance as Jake Holman in this film.
