Running time
Expected: 51'25"
Actual running time with bumpers: 51'46"
The bumpers between the acts are generally 10 seconds from fade in to the "End of Act" bumper to the end of audio before the commercial, a 10 second still without audio, then cut to the next act bumper. This would play with the theme for around 10 seconds. Accordingly, with the episodes being in 3 acts, the running time of the action is approximately a minute less than listed above, minus the opening and closing credits (normally 0'16", with a 2" fade, and anywhere from 0'41" to 1'20", hard cut or 1" fade or mix, respectively).

Minutiæ
- 4:14 - Kearns' calculations:
(4 x 3162)2 = 175... 8919... 2978... 304... oh, and so on and so forth.
apparently, contrary to what he says, it appears neither Kearns nor Plato can add up as the answer is 159539531776.
3259 / 263 = 12.39163498098 recurring - no, 8.. 2... [1 2 9] (spots Cathy) hello, hello, what have we here?
(It's actually 12.391634980986). - 9:28 - When Cathy says that Hurst is in a panic and wants "MI5, the Navy, whoever" Steed replies, "You he can have, I'm off to the Middle East tonight." Is this admission that the organisation is MI5?
- At the end of their discussion in the amusement arcade, Cathy says, "You're staying out of it?" and Steed replies, "Yep, you go right ahead, Mata Hari. Just send me a postcard."
- Pinball scores:
Cathy: 1970 Steed: 1280 and 1891 (well, it goes up a bit more, but we don't see the final score) - 24:28 - the camera takes a second to focus on Cathy when she turns on the light.
- 28:15 - the camera dips briefly as if it collided with something
- 38:42 (37:33) - One of those boom mikes sneaks into shot again while Steed is helping Cathy apprehend Broster and Clarissa.
- 39:15 - Steed identifies himself to the police as "Carruthers"
- 50:30 - instructions for caring for Sheba: half pound of meat, some seaweed powder, a special teaspoonful of cod liver oil and a long walk daily.
