Corrected entry: At the end of the movie, during "the last night", we see that the tree smashes through one of the windows in the attic. Later, when George returns to the house to get the dog, there's an outside shot where both windows are intact. (The famous windows are not on both sides of the house. Only the side facing the water).

Correction: The infamous windows are on one side of the house. Historical fact.
Correction: Windows are on both sides. It can be hard to tell though. It just mostly shows the one facing the lake.
