Plot hole: Tintin has a pretty sharp eye (as seen in his fight with Haddock, in the radio room, the Thompsons following them etc.), but he didn't notice that Sacharin's Unicorn was still fully intact? His own model was pretty badly damaged, with all sorts of wires hanging loose after its fall. (00:10:00 - 00:15:30)
The Adventures of Tintin: The Secret of the Unicorn (2011)
2 plot holes - chronological order
Directed by: Steven Spielberg
Starring: Daniel Craig, Simon Pegg, Jamie Bell, Andy Serkis
Continuity mistake: When Barnaby is shot, the newspaper keeps moving away/towards him between shots.
Tintin: We failed.
Captain Haddock: Failed. There are plenty of others willing to call you a failure. A fool. A loser. A hopeless souse. Don't you ever say it of yourself. You send out the wrong signal, that is what people pick up. Don't you understand? You care about something, you fight for it. You hit a wall, you push through it. There's something you need to know about failure, Tintin. You can never let it defeat you.
Trivia: Steven Spielberg was originally going to make this movie a live action movie with Snowy computer generated.

Chosen answer: He must have thought that Snowy had found the magnifying glass and was playing with it. Like most dogs would do with a toy.
