We got our first look at Steven Spielberg’s next big science fiction movie Ready Player One at San Diego Comic-Con earlier this year, and today, Warner Bros. released a new trailer on Facebook Live, with author Ernie Cline answering questions about the origins of the story.

Based Ernie Cline’s debut novel, Ready Player One is set in a dystopian world where almost everyone spends a majority of their time in a virtual reality system known as OASIS, where players can visit any conceivable world (allowing the book to mash up an incredible number of ‘80s pop culture references). The trailer opens with Wade Watts (played by The Tree of Life / X-Men: Apocalypse star Tye Sheridan) saying that he got his name because his father thought that it sounded like a superhero name. He then talks about OASIS, which allows people to do anything, and that people stay because they can become anyone.

The trailer then shows James Halliday, the founder of OASIS, who tells gamers that he’s died, but that he left behind a massive Easter egg hunt: whoever finds the three hidden keys will get control of the entire system. Wade is one such participant, who teams up with another competitor, Art3mis (played by Bates Motel’s Olivia Cooke), to find the three clues before a major corporation does.

Along with the trailer, Warner Bros. released a retro poster for the film that harkens back to the novel’s paperback cover. As Kotaku pointed out, there’s one thing that’s a little... off about it.

Ready Player One hits theaters on March 30th, 2018.
