First appearance of Mercy Graves.

John Rubenstein who voices Dr. Peterson played Dr. Vale, Metallo's creator, on Lois & Clark: The New Adventures of Superman.

(Nitto and Sam steal a diamante)
Sam: What do you think we'll get for it, Nitto?
Superman: I'd say five to ten. With time off for good behavior.

Sam: You know, he don't look so hot. Maybe we should help him.
Nitto: Sure, we'll send him a chicken soup. Come on!!

Lex Luthor: Well, next time you see one of my museums being robbed, call someone who can do something about it, like the police!

Lex Luthor: You work for me, Peterson, don't forget that! There shouldn't be an opinion in your head that I haven't put there!

(Clark stands in front of some rocks he thinks to be Kryptonite)
Clark: Nothing's happening.
Old lady: You were expecting them to dance for you?

Lex Luthor: As long as I have the rock, you can't stop me. But it is bothersome to have you always trying, so, the deal is this: you leave me and my operations alone, and I and my little green rock will leave you alone.
Superman: I don't make deals with criminals
Lex Luthor: I control everything in this town, Superman, your cooperation is not really necessary. The offer was merely a courtesy.
Superman: You will never control me, Luthor. Never! (flies away)
Lex Luthor: Well then, I guess I'll have to kill you.

Professor Hamilton: The fact that your body chemistry absorbs the radiations so readily, leads me to believe that you share with it a point of origin.
Superman: You mean it came from Krypton?
Professor Hamilton: More than likely it is Krypton, or rather a small piece of it. 'Kryptonite' if you will.

Lex Luthor: Ah, Professor, Mercy will see you safely home now, won't you my dear?
Professor Peterson: Please, no! I-I-I mean, I can see myself home, really!
Lex Luthor: But I insist. Metropolis can be such a dangerous city, Peterson. I'd hate to wake up tomorrow and find out that something terrible had happened to you...

When Mercy shot at the Kryptonite, it should have shattered it like the glass.
