Other mistake: There's a typo in the end credits - an extra S in "3rd Asssistant." (02:16:30)
Other mistake: When Finn and Rey see Han talking to Ben on the bridge, they look directly down. But the platform they're standing on is to the right of the bridge. If they're looking directly down, they would be looking at either the floor or the chasm around the bridge. They should be looking to their left.
