- Awesome Music: "In the Court of the Crimson King" was just a great choice, because the song's majesty is so ironic given the sad state of the world.
If you thought things had changed friend, you'd better think again. Bluntly put, in the fewest of words: Cunts are still running the world.
- A lot of the soundtrack could qualify, as could the sound-scape of the film in general, but special mention has to go to Jarvis Cocker's Running The World played over the end credits. The lyrics are a thing of beauty.
- Darkness-Induced Audience Apathy: The problem some detractors have with the film. Most characters act completely reprehensible, anyone who does have a shred of likability is killed fairly quickly after they appear, and even the hero is dead by the end of the film. Though he is able to successfully evacuate Kee and her child to a save haven before his death, given the major Crapsack World setting any chance of it being a long-term recluse away from all the warring factions before it catches up to them is slim at best.
- Everyone Is Jesus in Purgatory: Let's see, a young pregnant woman traveling to a far-off place with a "miracle baby", accompanied by a guy who isn't the father of her child yet still loyally sticks by her to see her there. Sounds like Mary and Joseph to me.
- Gratuitous Special Effects: The childbirth scene. While this movie is sci-fi and usually averts this trope, a scene of a baby being born is usually filmed without the need of CGI.
- Hell Is That Noise
"Y'know that ringing in your ears? That 'eeeeeeeeee'? That's the sound of the ear cells dying, like their swan song. Once it's gone, you'll never hear that frequency again. Enjoy it while it lasts."
- The "Zen Music" Jasper listens to.
- The high-pitched atonal music that plays while Theo is trying to find Kee in the gun battle is an excerpt from "Threnody for the Victims of Hiroshima" by Krzysztof Penderecki. It's intentionally meant to evoke chaos, panic and fear. It's also a Call Back to the movie's use of tinnitus to indicate ageing.
- Harsher in Hindsight: It was mentioned that there was a flu pandemic in 2008. Strange, considering the swine flu pandemic in 2009.
- Even worse was the the Zika virus scare in early 2016. Many were concerned would cause a pandemic of children born without most of their brains. It even drew direct comparison to this film.
- Moral Event Horizon: During the battle in the refugee camp, a group of people try to surrender and are gunned down by the military.
- Most Annoying Sound: Baby Dylan's crying can get old pretty fast for viewers. That said in a world that's been devoid of an infant's cries so long it would certainly be the most wonderful sound. Robot Chicken lampooned this discrepancy, when their Children of Men spoof cut from soldiers admiring the bawling Dylan, to Kee and Dylan flying in an airplane, where the baby's crying annoys the hell out of another passenger.
- Never Live It Down: That stupid ping pong ball gag.
- Retroactive Recognition: Wait, Raleigh Becket was once a terrorist? Must have been back when he called himself Jax Teller.
- The Axeman is a nice guy who loves art.
- Sci Fi Ghetto: Although the film is intended to be a thriller, banking on the chase with the set-up being necessary to justify the story, the sci-fi concept of a future with no children meant it should've fallen squarely in this trope. And yet, the critics loved it. Didn't quite make back its own budget in theatres, though, and several critics seemingly go out of their way to call it anything except science fiction (terms like "political thriller" were thrown around here and there).
- Not to mention the fact that it was nominated for three Oscars: Editing, Cinematography and Adapted Screenplay.
