This Video Points Out Every Easter Egg, Reference and Cameo in READY PLAYER ONE
I've seen Ready Player One twice so far and I know that I haven't seen everything that is packed into that movie. I just watched this video from Mr. Sunday Movies and he lists every Easter egg, reference, and cameo that he noticed in the film and I didn't see half of the stuff that he mentions on my first two viewings! Chances are I won't notice all of them until I own the film and am able to pause it and take the time to scan it. If you're a fan of the movie, you'll want to check this video out. After you watch it, let us know if you were actually able to catch everything that is pointed out in the video. There are spoilers in this video though, so if you haven't seen the movie yet, I suggest that you don't watch it.
Out of everything that he mentions, there is one character he missed, and that character is Spawn, and he also missed the Glaive from Krull.
