History ComicBook / DCTheNewFrontier

* ComicBookFantasyCasting: WordOfGod states that Hal Jordan is based on Creator/BurtLancaster.

* AlternateContinuity: Relative to the main DC universe. In the collected edition, space-time-traveler ComicBook/RipHunter shows up in a short prologue to basically say it's not important which time or Earth this takes place on.

* PrecisionFStrike: [[spoiler:John Henry, wounded and hiding from the Klan, begs a little girl for help. Her response: "The '''nigger's''' over '''''here!'''''"]]

* AmericaSavesTheDay:

** Also Martian Manhunter chose to return to Mars after seeing some people are apathetic towards Flash quitting.

* WhatHaveIBecome: Part of Batman's motivation in changing his look and methods. He realizes that he's taken the dark avenger thing a little ''too'' far and has become a monster to the very people he's trying to protect.

* BookEnds: The comic ends with [[spoiler:the Justice League confronting Starro, echoing the classic cover of ''The Brave and the Bold'' #60.]]

* MythologyGag: Captain Nathaniel Adam sacrifices himself by detonating the atomic bomb he's carrying. Don't worry, [[ComicBook/CaptainAtom he'll get better]], eventually.

* ADayInTheLimelight: Hal Jordan, the Martian Manhunter, and the Flash are the POV characters while the big name characters Superman and especially Batman are relatively OutOfFocus.

* RRatedOpening

* RRatedOpening

* ClicheStorm[=/=]{{Troperiffic}}: {{In-Universe}}; ComicBook/MartianManhunter bases his human identity of John Jones on detective shows. As a result, John Jones is the single most over-the-top detective you have ever seen. Slam Bradley thinks he's ridiculous, but likes him since he's one of the few good cops in Gotham.

** AdaptationExpansion: In the comic, Batman opts out of participating in the final battle, feeling as though he would be more helpful backing the heroes through Wayne Enterprises instead. In the film, he takes over Green Arrow's role in the fight.

---> "''My instincts tell me that you're to be trusted. But make no mistake: it took a $70000 sliver of meteor to stop [[{{Superman}} the one in Metropolis]]. With you all I need is a penny for a book of matches''."

* UsefulNotes/ColdWar: Hence the SuperRegistrationAct

* DeliberateValuesDissonance: It's the 1950s, when [=McCarthyism=] is at its height. Hal Jordan is treated like a coward because he doesn't want to kill people, and Flagg thinks this makes him a Communist sympathizer.

* EndOfAnEra: Part of the story deals with the transitation from the Justice Society to the Justice League, along with superheroes with more scienctificaly-based origins compared to most of the Justice Society's magic.

* IntrepidReporter: Lois Lane, who is firmly on the government's side at the beginning of the story.

* LetsYouAndHimFight: A Superman vs. Batman fight broke over the SuperRegistrationAct. Batman won. [[spoiler: Though it turns out the fight was staged so Superman wouldn't have to arrest his buddy]].

* RedScare: Considering it's the [[DirtyCommunists McCarthyism period of the 1950s]], there is notable paranoia and discrimination occurring over who is a communist sympathizer. The Flash was even accused of being a communist sympathizer due to his red costume.

* SlidingScaleOfIdealismVersusCynicism: It ''actually'' slides during the course of the story. It starts pretty cynical, but slowly gets more idealistic as the story progresses. How idealistic? The story ends with ''the friggin' formation of the '''Franchise/{{Justice League of America}}''''', that's how much.
* SocietyMarchesOn: In the Silver Age Green Lantern books, Hal used to call his sidekick Tom "Pieface," a slur for Asians. He uses the name exactly once in ''New Frontier'', and Tom immediately snaps at him and grabs him by the front of his shirt.
-->'''Tom''': What did you call me, white-bread? Do I look like a pastry to you or something? The name's '''''Tom, got it?'''''
-->'''Hal''': Whoa...'''''Tom'''''. I got it. I got it.

* WhatHappenedToTheMouse: Faraday reveals [[spoiler:Hourman]] is still alive and in a government cell, but he's never seen or mentioned again. Not even after the world's saved and everyone decides to work together.

The comic was given an animated DirectToVideo film adaptation titled ''Justice League: The New Frontier'' in 2008, with the voices of [[Series/{{Angel}} David Boreanaz]] as Hal Jordan, Kyle [=MacLachlan=] as Superman, [[Series/LawAndOrder Jeremy Sisto]] as Batman, Creator/LucyLawless as Wonder Woman and Creator/NeilPatrickHarris as The Flash. Creator/KeithDavid's baritone voiced the omninous and faceless Center. The film was produced by veteran Franchise/{{DCAU}} man Creator/BruceTimm and paid strict attention to the comic, lifting the majority of dialogue and scenes from the comic straight into the film.

Critical reception was enormously positive, the only complaint being how short the film was. Compared to other DTV comic book films, including those from {{Marvel}} and prior DC videos, this film was considered a breakthrough for mature WesternAnimation.

* BadassNormal: The American government has started recruiting these to make up for the lack of superheroes, so these show up a lot. Let's see, there's the Challengers Of The Unknown, The Blackhawks, The Suicide Squad, The Losers, King Faraday, The Sea Devils, ComicBook/GreenArrow... and Batman.

* AmericaSavesTheDay

Instead of reimagining the classic superheroes as they would be today, Cooke created a story firmly set in the [[TheFifties 1950s]] and took the superheroes as they were in UsefulNotes/TheGoldenAgeOfComicBooks and made them believable. Even the art work itself is very similar to comics of that era, with only the layout being modernized. The plotline is broad-ranging, featuring dozens of characters in the {{DC Universe}} including Franchise/{{Superman}}, Franchise/{{Batman}}, Franchise/WonderWoman, Franchise/GreenLantern, Franchise/TheFlash, ComicBook/MartianManhunter and many more.

* BigNo: The Center[[spoiler:, when he's destroyed.]]

* {{Cult}}: The unnamed purple robed men under the thrall of the Center that Batman dispatches.

* EldritchAbomination: The Center, a living island with the ability to spawn an army of even more eldritch-looking dinosaurs. [[spoiler:And is mentally linked to them, which is what does it in-the death of the T. Rex mentioned in DyingMomentOfAwesome disrupts its focus for a minute, leaving it open to a fatal strike.]]

** The reason for the Center to destroy them all. The first atomic bombs were the push he needed.

* StoryboardingTheApocalypse: A particularly creepy example, wherein the Center's plans for humanity are communicated via the writings of a children's author -- specifically, a Dr. Seuss {{Expy}}. Who then shoots himself.

* BigNo: The Center.

* EnemyMine: At first. The superheroes came to help the military, but they don't want their help. A soldier even threatens to shoot Flash, who's tempting him, if they don't leave. Fortunately, Superman arrives to stop it and calls them out for continuing their petty hatred with one another while the world is in danger.

** The reason for the Center to destroy them all. The first atomic bombs were the last straw.

** Ted Grant defends his title against a young black fighter named Clay but we never learn Clay's first name or see his face and he's also at least eight years older than [[UsefulNotes/MuhammadAli Cassius Clay/Muhammad Ali]]. In the movie he ''looks'' like Ali but is renamed [[CreatorCameo "Cooke."]]

* RedScare: Considering it's the McCarthyism period of the 1950s, there is a notable paranoia going on over who is a communist sympathizer. The Flash was even accused of being a communist sympathizer due to his red costume.

* WhatTheHellHero: Superman is shocked that Wonder Woman freed slaves and sat by and watched as they killed their masters. Wonder Woman argues that it was necessary for them to get their pride back, and that she's doing more than Superman is about it.

* EnemyMine: At first. The superheroes came to help the military, but they want nothing to do with them. A soldier even threatens to shoot Flash if they don't leave. Fortunately, Superman arrives to stop it and calls them out for continuing their petty hatred with one another while the world is in danger.

* HumansAreBastards: The reason for the Center to destroy them all. The first atomic bombs were the last straw. Also the reason why Martian Manhunter chose to return to Mars.

* MyFistForgivesYou: Flash is able to work with Faraday despite Faraday trying to arrest him. You know, after Flash punches him in the face.

* {{Ungrateful Bastard}}s: When Flash announce his retirement due to distrust from the public and the government, most people in the restaurant J'onn's eating at either don't care or are glad.

* BadassNormal: The American government has started recruiting these to make up for the lack of superheroes, so these show up a lot. Let's see, there's the Challengers Of The Unknown, The Blackhawks, The Suicide Squad, The Losers, King Faraday, The Sea Devils, GreenArrow... and Batman.
