Many Scene was pay tribute to past movies
- Fall to batcave(Batman Forever)
- Giant Bat Deleted Scene(Batman Forever)
- Graple gun Claw(Joel Schumacher)
- Fall of Superman(Superman Return)
- Son of Superman(Superman Return)
that was alittle bit tricky,bath scene means that superman have normal sex. He may have a son in the future. This scene also made a contrast with bruce wayne that he bath alone:D
- Lex Luthor use alien Technology(Superman Return)
- Lex use henchwoman without any mercy(Superman Return)
- Lex to Superman,Joker to James Gordon.(Killing joke)
