Anthony Dawson: In the first appearance of the Ernst Stavro Blofeld villain character in a James Bond movie. His part is uncredited in the credits, which are attributed to a question mark. Dawson had appeared in 007 Contra o Satânico Dr. No (1962) as Professor Dent, and returned again as Blofeld in 007 Contra a Chantagem Atômica (1965). He was the only actor to have played Blofeld more than once, until Christoph Waltz took on the role for a second time in 007 - Sem Tempo para Morrer (2021), after portraying the character in 007 Contra Spectre (2015). They are now tied. The voice of Blofeld in this movie was dubbed by an uncredited Eric Pohlmann.
Bob Simmons: Regular stuntman is the actor appearing in the gun barrel sequence at the beginning of this movie. The same footage was used for the first three James Bond movies. The others being 007 Contra o Satânico Dr. No (1962) and 007 Contra Goldfinger (1964).
Jacqueline Saltzman: Wife of producer Harry Saltzman is leaning out the window of the Orient Express, next to the window containing Robert Shaw, as it leaves the station. The scene was shot on the real Orient Express.
Ian Fleming: (unconfirmed) Some reports maintain that Fleming appears standing next to the Orient Express train. He is wearing grey trousers and a white jumper and stands on the platform to the right side of the train. Other sources deny that this is him.
Terence Young: The director appears (uncredited) as an extra and as a body double (uncredited) for Pedro Armendáriz.
