The Death of Superman

At the weekly meeting of the Justice League, Cyborg tells everyone the meeting will be next week, "Same Bat time...same bat channel," which is the same phrase spoken after episodes of the 1960s Batman TV series.

When the submersible sub is ripped open by Doomsday, it is at approximately 6 miles below the surface, where the water pressure nears 16,000 lbs. psi. The pilot's bodies would have been utterly flattened upon exposure to this pressure, not left floating intact as if they were simply submerged in a pool.

There are 3 more scenes during the end credits. One of a specimen escaping from LexCorp, another of John Henry Irons at work, setting up Steel, and another of the Fortress Of Solitude. A 4th scene after the credits have ended is a glimpse of the Cyborg Superman, followed by a shot of the Superman "S" shield dripping blood.
