In Metropolis on the bridge, Doomsday grabs a soldier and breaks his neck and skull. In that shot, the soldier's arms are inside Doomsday's hand and his hair is a light brown or gray. But then when the shot changes as Doomsday begins to throw the soldier to the side, the soldier's arms are suddenly outside of Doomsday's hand, and his hair is now black.
After Doomsday breaks out, he jumps at the laser drill rig and punches through the driver compartment and rips out the guy inside. When he throws him, this guy cries out in the iconic Wilhelm scream.
