If the trailers for Ready Player One weren't proof enough that this might be the most nostalgia-packed movie of all time, this should do the trick. Warner Bros. has released 12 new posters for the film, each of which takes inspiration from a classic movie.

The homages range from Back to the Future to Steve McQueen's Bullitt to The Iron Giant--a movie whose main character has been heavily featured in Ready Player One's promotional campaign. These images are perhaps the best way to sell a movie like this.

The story, based on the Ernest Cline novel, is set in a near-future dystopian world where people escape from their overcrowded cities into a virtual world filled with fictional characters, objects, and settings from their favorite pieces of pop culture. Why not take advantage of the pop culture audiences already love to sell them on this escape of a movie?

Interestingly, though Steven Spielberg is the director of Ready Player One, none of his movies are represented in the posters--there are titles in which he served as a producer, though. Ready Player One hits theaters on March 29. Take a look at each of the new posters and the movies that inspired in this gallery.
