This episode was originally conceived as two separate episodes, but the CW budgeted extra money, promoted, and aired it as a single two-hour movie event. The two episodes would have been titled "Society" and "Legends". Due to this change, this is the first, and so far only episode to have two words in its name instead of one.
The characters in the JSA portrait, left to right, are: The Star-Spangled Kid, Wildcat, the Golden Age Atom, Sandman, the Spectre, the Golden Age Flash, Hawkman, Hawkgirl, Dr. Fate, the Golden Age Green Lantern, Hourman, Dr. Mid-Nite (with Hootie the owl), the Golden Age Black Canary, and the Golden Age Mr. Terrific.

Paul Kupperburg and Steve Erwin are noted in the end credits as the creators of Checkmate.
Sylvester Pemberton: You're the one they call Watchtower.
Sylvester Pemberton: Technology today makes hiding a whole lot harder, Miss Sullivan. When someone like you reaches out and plugs into so many outlets, someone else is bound to pull out one of those cords and follow it back to the source.
Oliver: Is that my e-mail? Chloe, I'll have you know that those messages between me and Canary are purely platonic?
Kent: Red, white, and blue. Two betrayed. Stars and Stripesy, stars and stripe. Sandman doesn't dream anymore. Is Mister Terrific still terrific? I don't think so.
Clark: Who's that?
Kent: Who is that? Who is that? Kent Nelson. Dr. Kent Nelson. But the doctor is out. He's gone bowling.
Carter: My friend is very sick.
Kent: Ticktock. The Hourman's run out. The Atom is split. No, he doesn't. He doesn't, Nabu, so stop whispering.
Carter: Look at Kent Nelson, Courtney. He spends most of his days wandering the streets, searching for the secrets to the universe at the bottom of trash cans.
Courtney: So, Dr. Fate is incapacitated. The Sandman and the Star-Spangled Kid are both dead. You were their leader. What's your excuse? Please don't make me ask another team for help.
Carter: Oh, the kids out there playing hero are hardly a team. They don't know how to lace up their own boots.
Courtney: Well, maybe if you had laced up your boots when Sylvester had asked you to, he might still be alive.
Carter: Don't waste your breath. I have enough guilt to last 20 lifetimes.
Kent: Please, Nabu, don't whisper too loudly. Don't show me what could be or not be. Fate is a fickle thing.
Carter: It's been a long while since I've made someone bleed. Time to go hunting.
Green Arrow: Red, white, and blue. Loud and proud to be an American. Nice.
Stargirl: Well, at least I'm proud of something other than myself.
Green Arrow: What's that supposed to mean?
Stargirl: I know what kind of hero you are, Green Arrow.
Green Arrow: Is the masked cheerleader really talking down to me?
Clark: But none of us here are the bad guys.
Green Arrow: You sure about that, Clark? The winged warrior here threw me through a window.
Hawkman: I hope I didn't make you cry.
Green Arrow: Drop the mace, Conan.
Hawkman: I will... on your head.
Green Arrow: Bring it, big bird. Just for the record, you started it.
Hawkman: I'll finish it.
John Jones: I hope it's not too late to say, "We come in peace."
John Jones: Even when I had the power to leave Earth, I chose not to, for one reason--hope. Hope for the future. Humanity's capacity for violence is great, but their capacity for hope is greater than any I've ever encountered.
Carter: I wasn't the leader they thought I was. I made too many mistakes.
Clark: I've made mistakes, but I haven't quit.
Carter: Haven't quit? You haven't started. Not as a team, anyway.
Clark: You're making this too personal.
Carter: That is our strength, not our weakness.
Green Arrow: I hate waiting.
Hawkman: But you love talking. Shut up.
Oliver: What are you--my chaperone?
Hawkman: Think of me as your parole officer but with a mace.
Oliver: Well, I don't know what that means, but this whole thing is bad news. You want to know why? 'Cause no one's been able to answer "why"?
Hawkman: Why what, green punching bag?
Dr. Fate: But when I see the future of someone such as yourself, I believe in tomorrow again.
Clark: When you saw my fate, what did you see?
Dr. Fate: You will lead this generation as Hawkman once lead ours.
Clark: You sound like a group I met from the future. They hinted at my destiny, but they were as vague as you are.
Dr. Fate: Then let me be specific. Although Lex Luthor is your ultimate opponent, you will triumph over him.
Clark: Lex? Lex is dead.
Dr. Fate: And when you show yourself to the world, it will be a different age than ours, Clark--a Silver Age of heroism. That will start when they look up into the sky at you with hope for tomorrow. You will help everyone embrace it.
Clark: Lois? What's she doing here? She shouldn't be in the middle of this.
Dr. Fate: She is the key.
Dr. Fate: Greetings.
Lois: What the...? What is this, reverse Halloween? Nice helmet.
Dr. Fate: Thank you.
Dr. Fate: I see your fate, Lois Lane. You are the one he will need. He is the one you will need.
Dr. Fate: The savior... the one who will lead us all... the sentient power.
Green Arrow: I'm thinking we should regroup with the others before we go after Icicle Junior.
Hawkman: You go back to Sherwood, Robin Hood. I'll turn the Icicle into slush myself.
Green Arrow: You know, you really got to work on your landings.
Hawkman: It would have been a lot smoother if you hadn't thrown up.
Green Arrow: Send me your dry-cleaning bill.
Hawkman: Send me your dinner bill.
Clark: They're the best friends that I have, Carter, but I don't know if we'll ever be what the JSA was.
Carter: You have to trust them.
Clark: I do.
Carter: You have to remember they're people, too. They'll make mistakes. We all do. We all have to keep trying. Isn't that what you said?
Carter: You know, I only learned to fly after my kingdom was attacked and taken from me. It was only then I realized it wasn't the throne that was important. It was my people... my wife.
Clark: What about you? You going to keep your wings locked up?
Carter: No. No. No, I am putting people under them. Chloe helped Courtney and I locate the remaining members of the JSA, their children, and their proteges. I think the coming generation could stand to learn a thing or two from those of us that have done it before.
Courtney: So what do you call your team anyway?
Clark: A work in progress.
Oliver: Anyone home?
Chloe: What's up?
Oliver: Nothing, actually. I, uh, I thought I'd stop by and see if anyone's hungry.
John Jones: I could use some dinner. Chloe?
Chloe: Uh, sure. You're buying, Mr. Queen.
John Jones: Don't look at me, I'm living off a policeman's salary.
Oliver: Ah, fine. Dessert's on you.
John Jones: On Mars, we never had dessert, but I have grown especially fond of cookies.
Clark: Do you believe in fate, Lois?
Lois: Only the kind you make happen.
Amanda Waller: There's an army of heroes growing. This generation and the last are coming together. And I'm going to need everyone if we're going to survive the apocalypse that is coming this way.
Icicle: Apocalypse? This is not what I signed up for.
Amanda Waller: Welcome to the Suicide Squad. (shoots him)
