Steven Spielberg’s Ready Player One — an action-adventure motion picture based on Ernest Cline’s best-selling book of the same name — got off to a running start this weekend, earning a solid $53.215 million at the box office.

Composer Alan Silvestri created the film’s incredible musical score, recorded at the famed Sony Scoring Stage in Culver City with over 100 members of the American Federation of Musicians Local 47.

“While all sorts of culturally iconic references populate Ready Player One, the score that Alan Silvestri composed is completely and intoxicatingly original,” Spielberg said in a statement. “It’s bound together by multiple themes that identify plot and character and is infused by such percussive adrenaline and soaring strings that Alan has made Ready Player One appear to fly. I think his score is fantastic.”

Ready Player One marks Silvestri’s first collaboration on a film directed by Spielberg, although he has scored a number of films where the filmmaker served as producer, including Who Framed Roger Rabbit? and the Back to the Future films.

“An invitation to travel arrived just about a year ago, not just to a place, but to a time.  Actually, to a number of times—primarily the year 2045, along with a few stops in the ’80s,” Silvestri said. “A rather detailed map had been drawn by Ernest Cline and the Captain of the voyage, none other than Mr. Spielberg himself. What could one possibly do or say? Pencil in hand, one firmly fastens one’s seatbelt, says ‘Sir, Yes, Sir,’ and prepares for the trip of a lifetime.”
