Hergé's Cameo Appearances / Blond Man Spotting
Tintin in America
Taking the beginning of the credits as 00:00, the blond man (Hergé) appears at about 15:30–15:40 as the scene changes from Smile's cabin to a room full of gangsters. The blond man is sitting in the front row, wearing a black tie. The dialogue immediately before and after the man's appearance is: ... the police are waiting ever since Tintin came into town...
Cigars of the Pharaoh
This episode has two Hergé appearances. First, about 18 minutes into the action, Hergé appears on Rastapopoulos' film set as one of the crew behind the camera when Tintin interrupts the action.
Later (at around 33:00), Hergé stands in the grounds of the mental asylum when Tintin is escaping.
The man in the foreground who is holding the pipe resembles Hergé's friend and collaborator, Edgar Pierre Jacobs. Jacobs created the famous Blake and Mortimer series. [Information courtesy of site readers, mct16 and Steven Gielen.]
The Blue Lotus
About three minutes into the episode, Hergé can be seen leaning on a lamp post checking his watch when Tintin arrives at Mitsuhirato's department store window.
Later (30:00), Hergé appears again sitting in a tea house in Hukow, just before Tintin meets Thomson and Thompson.
