Continuity: When Sunny picks up the Scrabble letter, you can see the remaining letters are stacked together. Later when the shot change to her smiling, you can see the letters are more scattered.

Factual error: When Klaus burns the hole through the certificate, Count Olaf looks right through the hole into the magnified sunlight. His eye would be severely damaged if looking into sunlight through such a powerful magnifying object.

Deliberate "mistake": When Violet and Klaus have the anchor on the three cans they use to roll it on, just before they tip it over the edge, it is obvious the anchor isn't a real anchor. It's too light. When they keep pushing it back and forth, it should tip over because of the weight if it was a real anchor. They shouldn't have been able to handle it like that.

Continuity: When the Baudelaires arrives at the Curdled Cave and Aunt Josephine says "You deciphered the clues in my note" she is holding both hands over the edge of the rock on which she is lying. When it cuts only one of her hands are over the edge.

Continuity: When Aunt Josephine hands over the photo album to Violet she hands it over with one hand. When it cuts she is holding it with both hands.

Continuity: When Count Olaf leaves the car on the train tracks and heads for the shop while locking the car doors with his remote, you can see that the mannequin's stop sign in its hand is pointing to the left. But when it cuts to Olaf hitting the sign it is pointing towards the camera.

Factual error: Olaf and Violet's marriage certificate bursts into flames after the light from the magnifying glass hits it. The papers would not burst into flames, despite the size of his magnifying glass, it should have just burned a hole. Obviously done to be dramatic.

Factual error: When Klaus first finds the Eye, if you look closely at the light beam just as it exits the eye, it is curved like a vortex. Light cannot do this; it should have been straight more like a cone shape.
