Some innocuous flirtation among a couple of adults. Such as a moment where after Mansley meets Hogarth, he stumbles across his mother Annie only to find himself oogling her for about a split-second by quickly dragging his eyes from her hips all the way to her bust.

We see a boy unzip his pants in a bathroom and is seen sitting on the toilet with his pants down, though his underwear is still on. A man unzips his fly and a squirrel jumps out (this is seen from behind).

After the Iron Giant gets shot by tanks, bazookas, machine guns, armed aircraft and other types of military artillery, it starts obliterating many tanks and armored vehicles after going into attack mode from thinking they killed Hogarth.

A deer is shot and killed by hunters. No blood is or wound is seen, only the body.

A man goes through the window of a boat and is knocked onto rocks on the shore. Hogarth sprints into a tree branch and quickly wakes up with a nosebleed from the impact.

Mansley grabs a Hogarth by the face and threatens him, and then swiftly knocks him out by putting a handkerchief laced with chloroform to the boy's face. Two boys almost fall off a roof; a boy gets knocked unconscious.

The Iron Giant took a bite into a power station and gets electrocuted (the scene is very noisy and scary).

A big robot carries a boy in his hand, towering above the trees, and the boy looks scared.

We see a brain on TV that moves across the floor by itself.

A lot of scatological humor (diarrhea, constipation).

"God," "hell," and "damn" respectively.

"Damn it" is used by the antagonist's boss when he phones him at home; 1 other use of 'damn'.

2 uses of 'hell' as an expletive.

A man uses a chemical covered handkerchief to knock out a boy.

A boy puts a laxative in a man's milkshake.

Some locals attribute a fisherman's story about the giant to "either whiskey or beer."

A government agent smokes and carries a pipe several times. It reflects the period in which this film is set.

A boy watches an old horror movie on tv; a giant brain starts eating a man's head, but the scene is cut off.

A fisherman's boat is sunk. However, the fisherman himself survives.

Hogarth hears something either upstairs or on the roof and slowly goes to find the source of the noise. Later, Hogarth slowly makes his way through a darkened forest (with his flashlight) and follows the destructive path of something obviously quite large.

In the "Signature Edition" a newly added scene shows the Giant having a dream containing his memories both on Earth and additionally shows a possibility where he originally came from. He remembers the other robots resembling him destroying a city and blowing up an entire planet which awakens him in fear.
