Continuity mistake: The scene where Sully and Carl break into the house, Sully breaks the window and most of the glass is still in it. The scene changes and less than a second later all the glass is gone.
Continuity mistake: Mr Sullivan gives the stolen snow blower to his ex wife's husband for safe keeping, suggesting a tarp in the back of the garage. In a subsequent scene the snow blower is back in Sully's pickup for all to see.
