You know that one perfect high note in the A-Ha song, “Take on Me?” The goosebumpy bliss of it? “Ready Player One,” with endless callbacks to the era of A-Ha, is that note as a movie, set in the future, in love with the past, and uncannily right of this exact moment. There could be no better director than Steven Spielberg to take on this movie about a virtual game filled with the cultural touchstones of the 1980’s, a decade he helped define for the generation who will now be taking their children to this film and re-entering their own childhoods. We are all Marty McFly, now, going back to the future in a Delorean.

Spielberg is as good as anyone has ever been at the craft of cinematic storytelling, and there has never been a story more suited to that craft than this one, based on the book by first-time author Ernest Cline, who co-scripted and co-produced, and who admits that his world view was in large part formed by the Spielberg movies he watched as a kid in the 1980’s. There is a lot of nostalgia in the film, but also themes that could have come from today’s news: the role of technology as a distraction and as an invasion of privacy and underminer of democracy and the idea of teenagers saving the world.

It is Columbus, Ohio, 2045, when “people have stopped trying to fix problems and are just trying to outlive them.” The world is a bleak and broken place and most people spend most of their time escaping reality via a massive, enthralling online world called The Oasis, invented by James Halliday (Mark Rylance) a shy, obsessive genius who is a combination of Steve Jobs, Bill Gates, Mark Zuckerberg, Walt Disney, and Willy Wonka. “They come for all the things they can do,” we hear, “but stay for all the things they can be.” Players can design their own avatar personas any way they want — with antlers or wings, beautiful or ugly, super-powerful, purple, any age, gender, or species.

Five years before this story begins, Halliday died, leaving his half-trillion dollar empire and sole control of The Oasis to whomever was the first to discover the “Easter egg”* hidden in the game, which required agility, puzzle-solving, and a comprehensive knowledge of Halliday’s life and the popular culture he immersed himself in as a child in the 1980’s.

In five years, no one has even found the first of the three keys that lead to the egg. Many people have given up. Those still seeking it are called “gunters” (egg hunters). Wade Watts (“Mud’s” Tye Sheridan) is a teenage orphan living with his aunt and her latest in a series of abusive boyfriends in what is essentially a vertical trailer park called The Stacks. The film’s opening scene is brilliantly designed, as the camera pans down a dingy, jerrybuilt column of shabby capsules, showing each occupant caught up in a different virtual reality scenario, from boxing to pole dancing, with just one woman growing real-life flowers, the only person who even notices that Wade is there.

Wade signs into The Oasis, using haptic** gloves and a virtual reality eyepiece, for yet another try at crossing a virtual version of a Manhattan bridge guarded by King Kong. His avatar is Parzival***, who drives a Delorean, and he has an online friend, an enormous, mechanically-gifted man named Aech (I won’t reveal the voice performer to avoid spoilers). And he is intrigued by a female avatar named Art3mis (again, no spoilers) who rides the red motorcycle from the Akira video game. While Parzival and Art3mis both insist they will not “clan up” (team up with other players, they end up forming an alliance that includes two other avatars, Sho and Daito.

The Nolan Sorrento (Ben Mendelsohn) is head of the rival online company, Innovative Online Industries, and he wants to be the one to find the egg so he can make a lot of money selling ads (he has determined the exact number of ads that can bombard users “before inducing seizures,” he crisply informs his staff) and charging for access. IOI has hundreds of researchers and gamers trying to find the egg. And it operates “Loyalty Centers,” essentially debtors prisons, where those who owe the company money have to work it off under brutal and impossibly Sissiphusian conditions.

Wade has to locate three keys and solve clues involving not just logic and intense research but empathy, clues that turn out to be wisely selected by Halliday, Willie Wonka-style, to find the right person to take over the Oasis. Spielberg himself has to locate three keys as a filmmaker and does so with as much grace, heart, and integrity as Wade, his own avatar through the story. The copper key is the game level, the action scenes and the next-level special effects, including the chase across the Manhattan bridge and a stunning set piece inside the Stanley Kubrick movie, The Shining, repurposed here with bravura wit and skill. The jade key is the nostalgia, with dozens, perhaps hundreds of 80’s references, from the iconic and enduring to the obscure and forgotten. It is not, as is too often the case, shortcuts to play into the audience’s emotions, but deployed, again, with consummate wit and skill as commentary, as surprise, and as a reminder of our connections to the pop culture that first excited and engaged us. And the crystal key, well, it has been said often that the theme of all Spielberg movies is finding your way home. Wade is a 21st century Dorothy in Oz or Alice in Wonderland — or David in “WarGames,” exploring a land of infinite magic and wonder — and danger — but learning that there’s no place like home.

*The use of the term “Easter egg” to describe secret features originates from the 1979 video game Adventure for the Atari 2600 game console, programmed by employee Warren Robinett.

**They make it possible for the wearer to “feel” or “touch” virtual characters and objects.

***Named for one of King Arthur’s knights, who devoted his life to the search for the Holy Grail.

Parents should know that this film includes extended real world and virtual peril and violence including chases, explosions, weapons, murder, brief crude humor, some sexual references, brief strong language
