||In the recap of the first movie shown at the beginning of this sequel, we see Superman as a toddler emerging nude from the meteorite cradle in which he arrived on Earth.
We see Superman and Lois in bed together. No nudity is shown, but the post-coital implication of the scene is clear. In a later scene, Lois walks around the Fortress of Solitude in only Superman's costume shirt and a pair of socks.
We see Superman & Lois kiss.
||There are a lot of action sequences involving hand-to-hand fighting, thrown objects, firearms, rockets, and even a flamethrower. Much of this is fantasy violence involving super powers.
We see clearly-fake blood in a fistfight scene. Despite the fakery, this remains a scene of one man beating another bloody.
Lois fires a revolver at Superman in his Clark Kent guise to force him to acknowledge his true nature to her.
A man fires a shotgun at himself at point-blank range. The man is from Krypton, so he is not hurt.
Astronauts are killed by asphyxiation due to purposeful damage to their space suits.
||There is an occassional curse word here and there but there is none in the film otherwise.
||Perry White & Lex Luthor smoke. There are no drugs involved.
Superman and Lois drink a glass of champagne in a brief scene.
||In the recap of the first film shown at the beginning of this one, we see the drowning scene where Superman is being dragged below the surface of a canal by a "necklace" made from a towing chain and a chunk of kryptonite.
Another scene that may frighten younger viewers is the main fight sequence between Superman, Zod, Ursula, and Non.
We also see a few military battles where the US government attempts to stop the three evil Kryptonians.
In this Donner cut of the movie, Zod is shown briefly using a gun to kill people. (This was not the case in the Lester cut.)
In a scene, Superman's father, Jor-El, appears in the Fortress of Solitude when Superman returns in a desperate bid to restore his powers. Jor-El manages to do so by sacrificing the last of his energy to reignite Clark's powers with a final farewell. However, this virtual second death of Superman's father is undone when Superman reverses time to undo all the events from his initial mistake
