Ready Player One: Every Pop Culture Reference In The Trailer

10. The Iron Giant

You can't really miss him, can you?

The Iron Giant's towering cameo in the Ready Player One trailer is the easiest to spot, given the sheer size of the metal behemoth and how distinctive he is.

Steven Spielberg has confirmed that the Giant will be a major character in the movie, which is great news considering the original Brad Bird movie is hugely underrated.

A shadowy ninja with a pair of katana blades can be seen to the left of the giant, but nobody has the slightest idea who this is just yet.
