| Number Two | There are two Number Twos with repeat appearances: Leo McKern appeared in three episodes, and Colin Gordon in two. With the exception of "Fall Out", this was the result of the actors performing their roles in two consecutive episodes filmed back to back. Colin Gordon was filmed in "The General" followed immediately with "A. B. and C." McKern was featured in the series' second transmitted episode, "The Chimes of Big Ben," and then featured in the next production episode to be filmed "Once Upon a Time." Three actors who portray Number Twos also appear in other episodes, possibly as different characters — Georgina Cookson ("A. B. and C." as party guest and "Many Happy Returns" as Mrs Butterworth/No. 2), Kenneth Griffith ("The Girl Who Was Death" as Schnipps/No. 2 and "Fall Out" as The Judge) and Patrick Cargill ("Many Happy Returns" as Thorpe, and "Hammer Into Anvil" as No. 2) — although this is ambiguous, particularly in the case of Kenneth Griffith's character. | Patrick McGoohan |
