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

  1. 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).
  2. 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?
  3. 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."
  4. Pinball scores:
    Cathy: 1970 Steed: 1280 and 1891 (well, it goes up a bit more, but we don't see the final score)
  5. 24:28 - the camera takes a second to focus on Cathy when she turns on the light.
  6. 28:15 - the camera dips briefly as if it collided with something
  7. 38:42 (37:33) - One of those boom mikes sneaks into shot again while Steed is helping Cathy apprehend Broster and Clarissa.
  8. 39:15 - Steed identifies himself to the police as "Carruthers"
  9. 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.
