Ready Player One: first trailer for Steven Spielberg's virtual reality game thriller

It's game on. Fans got a first look at Steven Spielberg's anticipated Ready Player One in Hall H on Saturday at Comic-Con.

Spielberg revealed the trailer for the film as part of an event at Comic Con in San Diego, marking his first film since his Roald Dahl adaptation The BFG.

The footage for the '80s-themed (but future-set) action adventure debuted during Warner Bros.' presentation, which included DC films and Blade Runner 2049. 

The footage sees star Tye Sheridan as Wade Watts, teenager and gamer on a high-stakes treasure hunt in the all-encompassing video game, Oasis, designed by the nostalgic eccentric James Halliday, played by Spielberg-favorite Mark Rylance.
