Continuity mistake: When Violet and Klaus make the tent inside their bedroom in Count Olaf's house, they set up the light with the faces of their parents on it in front of it. Except when it shows the shadow of the object outside the tent, the edge of the picture frame isn't showing when it should.
Trivia: The instrument that Uncle Monty plays to the children is called an autoharp, from the Appalachian mountains - it's like an accordion, but the piano keys have been replaced with harp strings. Billy Connolly can actually play this instrument in real life, and the song he sings to the children is a song about Scotland, Billy's homeland.
Count Olaf: I must say, you're a gloomy looking bunch. Why are you so glum?
Klaus Baudelaire: Our parents just died.
Count Olaf: [nonchalantly.] Ah, yes. How very dreadful. Wait, let me do that one more time. Give me the line again while it's fresh in my mind.
Klaus Baudelaire: Our parents just died?
[Olaf pretends to be shocked.].
Question: As we know, the magnifying glass in Olaf's tower started the Baudelaire fire. This is the same tool that Klaus uses to burn up the marriage certificate. If the magnifying glass was powerful enough to cause the Baudelaire mansion to burst into flames, which was 37 blocks away, why didn't the stage burst into flames as well?
