Early reactions from the Ready Player One premiere at the SXSW festival are coming in, and the response seems to be overwhelmingly positive.

Steven Spielberg introduced his adaptation of Ernest Cline's sci-fi book that's heavy on 1980s pop culture at the screening in Austin, and although there were a few technical hiccups, the film received a standing ovation from the audience as the credits rolled.

Ready Player One, which will be released in theaters on March 29, follows Wade Watts (Tye Sheridan), a teenager and gamer on a high-stakes pursuit in a VR-like video game world called the OASIS. The game's deceased creator James Halliday (Mark Rylance) set up a treasure hunt prior to his death, and the winner of the game will become the richest person on Earth and also get control of OASIS. But an evil corporation, led by Nolan Sorrento (Ben Mendelsohn), is also on the trail.
