Ready Player One Trailer Explained: 10 Things We Learned
6. Expect A Few DC Comics Cameos
Given this wealth of diverse intellectual properties converging in a single film, it's not unreasonable to view Ready Player One as the gamer's Who Framed Roger Rabbit. Although, for one, Wreck-It Ralph and Pixels rather it beat it to the punch bowl there; and for two, this is a giant melting pot of geek culture writ large, encompassing any and all mediums.
As such, it's only logical that comic book characters would also appear; and, given this is a Warner Bros release, it's only logical they be DC Comics properties. You shouldn't have to look too closely to spot The Joker, Harley Quinn and Deadshot in the trailer.
Still, continuing the digital theme, here they more closely resemble the characters as they appear in the Batman: Arkham video games than in the comics or the movies.
