Audio problem: When Michael Shannon fires his gun, you can hear bullet casings falling to the floor, as is normal with a semi-automatic pistol. However, his gun is a revolver, so the casings won't eject until the gun is opened and emptied manually before reloading. (01:07:10)
Audio problem: When the wolves attack Maurice and Philippe, the wolves make growls that only big cats (lions/tigers) would make.
Audio problem: Superman uses his heat vision against Cyborg that shot at him. Cyborg deflects it and the beam destroys a patrol car in the distance, that explodes in the background without a sound. (01:14:50)
Suggested correction: There is a sound of a small explosion. Considering the distance, and we're close to the heat ray grinding on his shield, it's pretty good sound editing. We should be hearing more of the shield anyway.
