Changes from the Book
Mitsuhirato's assistant, Mr. Lee, is shown to be a double agent in the service of the Sons of the Dragon, and it is he who replaces the Rajaijah Juice with a harmless substitute and delivers the real poison to his employer Wang Chen-Yee. In the book, this was done by another agent. Gibbons is not shown at all, and Dawson's role is much reduced, he is only shown as the police commissioner who calls in Thompson and Thomson, and does not appear to be in league with Mitsuhirato. (This is to create a subsequent continuity error in The Red Sea Sharks, as Tintin mentions having a "run-in" with Dawson despite not encountering him in this adaptation of the story.)
In the book, Chang's parents were killed in the flood, but in the TV episode, Chang is already an orphan and his orphanage get washed away by the flood. At the end of the story, Roberto Rastapopoulos tries to flee through the Blue Lotus club when the other villains are apprehended, but is himself caught by Thompson and Thomson. In the book, Rastapopoulos was apprehended along with Mitsuhirato. Also, this episode, unlike the book, doesn't reveal Mitsuhirato's fate.

The scene where Tintin witnessed Mitsuhirato and Dawson destroying a section of the railway line was based on the Mukden Incident; a staged attempted destruction of the Japanese Southern Manchuria Railway carried out by Lieutenant Suemori Komoto of the Japanese 29th Infantry Regiment Independent Garrison Unit near Mukden on the night of the 18th September 1931.
While the explosion failed to destroyed the section of the railway line (as a passing train drove over the damaged section and arrived at Mukden 10 minutes after the explosion), this incident was used a pretext for the Japanese Invasion of Manchuria by the Kwantung Army on the 19th September 1931 and the creation of the Japanese Puppet State of Manchukuo on the 18th February 1932. The publishing of the Lytton Report on the 2nd October 1932 condemned Japan and led Japan to withdraw from the League of Nations on the 27th March 1933.
- In part 1, when Snowy and the Prince are playing on the stepping stones, Snowy's paws at some points seem to be landing in midair even before he runs off the end.
- In part 1, before Mitsuhirato turns away from the window, his moustache is white.
- During two scenes from part 1, Didi has a different voice compared to the rest of the story before and after.
- In part 2, the assassin photographer's moustache disappears when Chang pounces on him.
- In part 2, in an aerial shot of the warehouse, the speaking characters do not move their lips.
- In part 2, when Tintin emerges from inside the oil drum, his sleeve seems to come out through the side of the drum.
- In some scenes, Tintin's white shirt collar is miscoloured.
