Other mistake: Near the beginning of the movie, Vin Diesel kicks open a guy's door and you hear Marcus Fenix from Gears of War. When the camera pans to the TV for a split second, Marcus is not seen anywhere.
Suggested correction: Marcus Feenix doesn't need to be on screen to be heard. If, for example you are playing online and another player is controlling Marcus, you wouldn't see Marcus on screen every time he speaks as you are controlling Dom Santiago and see the game from his perspective.
