'Ready Player One' Trailer Is "War for Control of the Future"

Steven Spielberg directs the adaptation of the novel.

Ready Player One is 1980s nostalgia to the extreme, but the latest trailer gets an assist from something a decade earlier.

The trailer is set to Merethe Soltvedt's cover of "Pure Imagination," from 1971's Willy Wonka & the Chocolate Factory. It's a fitting pairing for a film about entering the all-encompassing video game OASIS and the battle that ensues for control of it. 

Steven Spielberg directs future-set adaptation of Ernie Cline's novel and follows Wade Watts (Tye Sheridan), a teen on a treasure hunt to become master of OASIS following the death of its creator James Halliday (Mark Rylance). But an evil corporation led by Nolan Sorrento (Ben Mendelsohn) is on the trail as well.

"This is war, for control of the future," says Sorrento.

Warner Bros is opening Ready Player One March 30.
