Alfonso Cuaron is a master filmmaker and a gifted storyteller. He excels at telling entertaining stories whether they be about kids or adults. His Harry Potter film is still the most watchable and imaginative, and his earlier children’s movie, 1995’s A Little Princess, has enough power to still get me misty. Even when Cuaron sets his sights on a sex comedy (Y Tu Mama Tambien) he can’t help but turn it into an affecting art movie. This man just knows how to tell a good story. Children of Men, a bleak science fiction thriller, is just the latest example of how effortless Cuaron makes it all blissfully appear.

In the year 2027, and the world is on the brink of annihilation. It’s not plague or rampant warfare that are the obvious culprits. The reason for mankind’s end is something more natural and depressing — women have stopped being able to make babies. England seems to be the lone country with some fraction of stability. Illegal immigrants are rounded up and housed in refugee camps for deportation. Cages full of crying and pleading foreigners are on many street corners. In a world of danger and hopelessness, always count on the kindness of xenophobia.

Theo (Clive Owen) is a bureaucrat that combats the future with cynicism. He can barely escape getting blown up for his morning coffee. Theo used to be an activist and married to Julian (Julianne Moore), the current leader of the Fishies, deemed a terrorist group by those in power. She finds him and asks for one last favor. Her people need transit papers to get Kee (Claire-Hope Ashitey), a refugee, and Miriam (Pam Ferris), a former mid-wife, to safety. Then Theo discovers the importance of his assistance. Kee is eight months pregnant. The government would never admit that that the first baby in 18 years belongs to a refugee, and political groups would like to use Kee and her baby as a rallying point for an uprising. But first Theo must get her out of harm’s way.

The idea of a world of infertile women is fascinating and full of big questions. This dystopian future must confront its own mortality in a very real way. Theo asks a friend hoarding classic art why he bothers. There will be no one alive in 100 years to even see them. Miriam says strange and heartbreaking things happen to a world that forgets the sound of children’s voices. Plenty of heady discussion is generated from a premise that affects every person on the planet. Why can’t women have babies? No explanation is given and none would seem credible. A religious faction believes this is the punishment of a vengeful God. People forget what babies even look like and what is commonly done for their care. The film also has a stark and timely portrait about the treatment of illegal immigrants. Children of Men is an intellectually stimulating movie that never rubs your nose in it. It trusts the intellect of the audience enough to leave many unanswered questions left to chew over and debate long after the movie ends.

The answers Children of Men finds seem reasonable and appropriate. Home suicide products exist for people that want to take back some control over their life, or at the least, are sick of waiting for the even more inevitable. It also seems entirely likely that this future world would turn the youngest living person (“Baby Diego” at 18-years-old) into a celebrity worthy of incredible mourning upon his untimely demise. These coping elements feel dead-on and only enhance the realistic tone of the film.

The film is a beguiling think piece but it also succeeds magnificently as a straightforward thriller. The majority of the second half is built around chase scenes and navigating to perilous outposts of safety that eventual crumble. Cuaron has a dizzying sense of believability as he puts together his world, and his roving camera feels like an embedded reporter on the front lines of chaos. The gorgeous cinematography and realistic set design contribute to the visceral sensation Cuaron sets alive with his visuals. There are long stretches where the camera continues rolling for nine minutes uninterrupted. I was left spellbound and felt trapped in this world just like the people onscreen. I was also wondering how much planning it took to coordinate and choreograph these long takes.

There are two very memorable scenes to quicken the pulse and both of them involve Cuaron’s mobile unblinking camera. The first involves a car chase perhaps unlike any I’ve ever seen before. Theo is leading an escape at dawn and robs the other cars of their keys. However, his own escape car refuses to start and the bad guys take notice. The sequence seems to last forever as Theo is forced to literally roll the car down a hill to outrun his pursuers who continually catch up with him. The second sequence follows Theo making his way through a refuge camp in the midst of a violent uprising being put down by heavily armored government troops. We watch every excruciating second of his survival as he navigates past gunfire, tanks outside a hotel, and then climbs through the different levels of the hotel being bombarded until we see, at a distance, where Theo’s trek all began. Exhilarating might just be the best word to describe Children of Men.

But nothing feels cheap or too sentimental in this world. This is a harsh and dark world where anything can happen, so the audience is left in constant peril worrying about the fates of every person onscreen. Like Casablanca, it strips away idealized notions of bravery and duty and just shows humanity for what it is and what it can be. That is gutsy but then that’s Cuaron as a filmmaker.

Speaking of Casablanca, Owen seems like a modern-day Bogart in this role. He’s ruggedly good looking but also a sly charmer. I’ve stated before my undying man-crush on Owen and Children of Men has only added to it. Owen has a remarkable way of playing detached but still noble and conflicted. He has the best slow burn in movies. The moments of wonder for him become our moments of wonder and worry. The rest of the actors appear in limited functions but provide good work. Michael Caine practically steals the movie as a crude yet philosophical hippie.

This is science fiction at its best. Children of Men is stark and realistic and truly immersive; you really feel like a member of this tumultuous future. It works simultaneously as a thought-provoking what-if scenario and as an exciting thriller. Simply put, this is a highly engrossing movie that separates itself from the pack. Cuaron has created a disquieting and entertaining sci-fi think piece that succeeds on its numerous merits. I knew half way into the movie that the newly minted wife, Mrs. Me, was only going to want a baby more from what we were watching. At least she now has a new argument: “It’s for the good of humanity.”
