Series 2 - Episode 5
Mission to Montreal
Teleplay by Lester Powell
Directed by Don Leaver
The original camera script lists the extras as: "Margot Lane, Barabara Straight, Dorothy Watson, Joan Smith and Messrs. (Richard) Pescud, (Bill) Richards, (Perry) Leigh, (Howard) Kingsley, (Paul) Blomley, (Robin) Kildare, (David) Low, (Alan) Crouch, (Melvyn) Mordant". Annotations in parentheses are my own comments, first names and roles are supplied by the wardrobe and makeup requirements sheet.
Perry Leigh may be a misprint for Terry Leigh.
