Continuity mistake: Leah asks Moose if he brought the cutters, so he looks in his bag then hands Leah scissors. In the shots facing Leah she holds up the scissors by its handles, but in the shots facing Moose she holds up the scissors by its pointy end. (00:10:20)
Continuity mistake: Moose is sitting at a desk writing a letter to Mr. Dunbar in a spiral bound notebook. There is a magazine to the right of the notebook with about the same width. After a couple quick camera shifts, the notebook is suddenly stacked on top of a few magazines and whatever Moose is writing on is obstructed by the stack. After a couple more quick camera shifts, the notebook is back in front of Moose, and he tears out the page he was writing on. (00:25:55)
