The closed captioning for this episode misspells Grodd's name as "Grog" and Aztek's as "Aztec".
The "safety deposit box" that the Flash pulls out is clearly much shorter than the Spear that we see in the next scene.
When Lex turns on the lights and there's a long shot of the villains, there's clearly a support pillar and crates off to their right. But then the camera angle cuts to behind them and to what was their "right" is now an open space and a door.
Luthor: Let them go. They're pathetic, but they're with me.
Luthor: Does the mystery man have a name?
Grodd: No reason to be insulting, Lex. I'm far superior to any man.
Luthor: I should kill you.
Gorilla Grodd: But you won't.
Luthor: No. (pause) Not today.
Gorilla Grodd: The Spear of Longinus. Hitler believed that whoever holds it is invincible.
Lex: What are you going to do with it? Sell it to the highest bidder? Keep it to yourself and try to conquer the world?
Gorilla Grodd: I was thinking it would look good on the wall in my office.
Luthor: You mean you recruited me, sent me to an island full of death traps, and up against the Justice League. You made me risk my life, and all for nothing?!?
Gorilla Grodd: Essentially...yes.
Luthor: (laughs) Monkey, I like your style.
Chuck: Whoever you guys are, you've got no business being in here.
Dr. Polaris: Sorta goes with the territory - we're thieves.
Flash: War Wheels, robot condors. You got a pretty goofy security system here.
Chuck: Yeah. Good times.
Shayera: Don't you ever scare me like that again!
Flash: She loves me. She's like the big sister I never had. Only...you know, short.
Shayera: He told you to drop him?!?
Fire: He's a senior member of the team.
Shayera: You know he can't fly, right?
Flash: Hey, ladies! Check me out! I'm just like a helicopter! Whoaaa. (crashes) I'm sorta like a helicopter.
Fire: You haven't said a word the whole trip.
Fire: I was hoping this mission would give us a chance to get to know each other a little better.
Flash: Um, umm, something...
Fire: I understand - you're very deep in thought, mentally preparing for the battle. No time for women - I understand.
Shayera: Why don't you just go talk to (Fire)?
Flash: Who, me? Talk to her? No way.
Shayera: Yeah, you'd probably be wasting your time anyway. I hear she's... you know... Brazilian.
Shayera: If you're afraid to talk to her, I'll tell her for you.
Shayera: You are so very sad.
Warden: My people can handle this.
Agent Faraday: Your people are good - Luthor is better.
Shayera: Why would you even try to move a prisoner that dangerous without calling us?
Warden: Maybe because we thought we could do our jobs without help from the mighty Justice League.
Shayera: And yet...here we are.
Flash: Now why is it you always find the Keys in the last place you look?
Chuck: Sorry – if I was 20 years younger…
Lex: You'd still be ancient.
Shayera: We going to do this the hard way, Lex? Please say yes.
Flash: Sure hope I think of something before I hit the ground.
First aired on YTV in Canada on February 1, 2006.
Among the costumes in display as the Leaguers rush through the Blackhawk Museum are those of Killer Shark, Queen Killer Shark, King Condor, the Hoopster, Blackhawk (1950s version), Chop Chop, Blackhawk (1960s version), Blackhawk (1970s version), and Lady Blackhawk.
The opening credits use the same music, but now use a shot of the Watchtower, Fire (from "I Am Legion"), the Red Tornado (from "Panic in the Sky"), Black Canary ("Double Date"), the Question ("Question Authority"), Dr. Polaris and then Dr. Polaris, the Key, and Lex Luthor ("I Am Legion"), the Javelin ("Hunter's Moon"), the Javelin fleet, Shining Knight & Vigilante ("Task Force X"), Supergirl, then Green Arrow ("Initiation"). It appears as if the producers are reusing the Mission: Impossible technique of including some "preview" scenes from the episode in the credits - those above indicated as being from "I Am Legion" change in the next episode.
Clancy Brown, Corey Burton, Powers Boothe, and Scott Patterson reprise their roles of Lex Luthor, Brainiac, Gorilla Grodd, and King Faraday. The actors playing Aztek, Fire, the warden, Dr. Polaris, and the Key are uncredited.
Scenes at the end are from "Shadow of the Hawk" and "Chaos at the Earth's Core."
Working Title: "We Are Legion."
The robot sharks that attack the Leaguers have laser beams on their heads. Alluding to Austin Powers: International Man of Mystery, where the bad guy's fondest wish is to have "sharks with frickin' laser beams attached to their heads!"
The Legion of Doom
Although Grodd never gives the name of his supervillain organization, the general shape of the HQ and its location in a swamp is clearly an allusion to the Legion of Doom, the supervillain organization that first appeared in Challenge of the SuperFriends. The Superfriends' first actual super-powered opponents, the Legion featured thirteen members: Lex Luthor, Brainiac, Solomon Grundy, the Riddler, the Scarecrow, Bizarro, Cheetah, Black Manta, Giganta, Gorilla Grodd, Sinestro, Captain Cold, and the Toyman. Nine of those villains appear in the JLU version seen here. Each week the Legion would come up with some ludicrously overly complicated scheme to take over and/or rob the world, be defeated by the Superfriends, but escape at the last minute. Various incarnations of the Legion have appeared in the comic books and clearly their use here is a homage to the 1970s TV series.
The title refers to a passage in The Bible, Mark 5:9: "And he asked him, What is thy name? And he answered, saying, I am Legion: for we are many."
