LOS ANGELES (AP) - Steven Spielberg said he didn't want to include too many references to his own films in "Ready Player One."
His films provided a source of inspiration to the book's author Ernest Cline who has his main character driving the DeLorean from "Back to the Future" and using a grail diary from "Indiana Jones and the Last Crusade."
Spielberg ultimately left a few nods in including the DeLorean, but nixed others like the mothership from "Close Encounters of the Third Kind."
"Ready Player One" imagines a near-future where society has abandoned the real world for an escapist virtual reality existence populated with 1980s nostalgia. It opens nationwide Thursday.
