First of all, a spoiler warning: If you haven't seen “Star Wars: The Force Awakens” yet, don’t watch the video and read no further. For everyone else who has already taken part in the media phenomenon, here’s a chance to discover dozens of Easter eggs, hidden references and bits of trivia from director J.J. Abrams’ "Episode VII."

Created by the talented YouTubers at New Rockstars, this 45-minute video goes over the whole movie with a fine-toothed comb to uncover more than 40 interesting nuggets that most viewers probably missed. (Hardcore fans out there will have spotted many of these details, but I doubt very many people noticed all of them. For example, how many "Game of Thrones" actors did you spot?)

Many movies contain references, inside jokes and other hidden messages, but Abrams tends to include more than most film directors. Not only that, but because "Force Awakens" is part of an existing franchise with a rich history, there’s a lot of material to draw from. Characters who might only have appeared in the background of one scene of the original “Star Wars: A New Hope” or “Star Wars: The Empire Strikes Back” pop up again, old props are re-used, even the voice of a long-dead actor can be heard. Add to that the many pieces of the puzzle that were mentioned by the cast and crew during interviews (like do you know the gender of the droid BB-8?) and we’re getting into some seriously deep analysis of the "Star Wars" universe.

Then there’s the whole layer of speculation about various questions raised but not answered in the movie, and some potential parallels with medieval legends. (Did the writers really base pivotal characters on the story of King Arthur and his Knights of the Round Table, and if so, could that give clues as to where they’re going in the second installment of this trilogy?)

Put your thinking caps on.
