Jor-El: (takes a deep breath, and holds up a single green crystal) He will not be alone. He will never be alone.
In the scene where Kal-El lands on Earth, there were two heartwarming moments on his part. The first thing he does upon meeting Martha Kent is hug her. The second, which becomes a Wham Episode for them, is when he stops the car from crushing Jonathan. It goes to show that even as a kid, not all his kindness came from their influence. It also gives the impression that the Kents didn't find their new son: he found them.
The scene where Superman saves the little girl's cat out of the tree. During a busy night of last-minute rescues, stopping criminals, and saving Air Force One, he's still finding time to be helpful with everyone he can.
The conversation between Superman and Jor-El after Superman's first night as a superhero in the extended cut.
Perry White: (snatches the address wearing a look of surprise) I'll see what I can do.
Clark: Oh, um, uh, thank you very much, um, Mr. White.
Lois: (bashfully) Any more at home like you?note This was an incredibly anachronistic quip that counts as Parental Bonus, even Grandparental Bonus. "Any more at home like you?" comes from the song "Tell me, pretty maiden," in an 1899 musical, Florodora. The line became a meme, used in innumerable cartoons, other stage shows, jokes, satires, films, etc. People were still using it in the 1950s; perhaps Lois got it from her mother or grandmother.
Clark: Not really, no.
However, the "Not really, no." can also double as a quick tearjerker considering his origins.
When Superman tells us everything we really need to know about him:
Lois: Who... are you? Superman: A friend.
And it's entirely the way Reeve sells it, that you can believe his sincerity the way he smiles as he says it.
As he's about to take Lois flying around Metropolis:
Superman: Ready?
Lois Clark...says you're just a figment of somebody's imagination, like Peter Pan.
Miss Teschmacher kisses Superman just before she frees him, and her dialogue makes it obvious she doesn't really have any ill will towards him.
The final shot of the movie, with Superman flying off into the sunrise. Christopher Reeve looks at the camera, smiles and flies off, leaving the audience with a dose of optimism. All of the consequent films up to Superman Returns would end in the same way.
The Movie
During production, Geoffrey Unsworth had a habit at work that Margot Kidder always found deeply flattering. Namely, when he was arranging the lighting for Kidder's scenes, he would order, "Quiet! I'm lighting the Lady!"
Christopher Reeve has said in an interview that at one point he was exhausted and frustrated from filming, but what got him back into the movie was listening to John Williams's compositions for the film.
The music, the dialogue, even the costumes and sets. I mean... damn. But even before that...Lara: He'll be isolated. Different... Alone.Jor-El: (takes a deep breath, and holds up a single green crystal) He will not be alone. He will never be alone.
