It is easy to get lost in Avengers: Infinity War. It’s got more dudes in costume than San Diego Comic-Con, it’s non-stop action from beginning to end, and its villain wants nothing less than wiping out half of all life in the universe. But if you’re watching closely through the entire film, you’ll spot a whole bunch of references and homages to Marvel comic books and movies past.

Yes, it is Easter egg time today at ScreenCrush, and the list below has ten of our favorites from Avengers: Infinity War. There’s an amazing shoutout to the first Avengers movie by Joss Whedon. There’s several callbacks to The Infinity Gauntlet, the classic ’90s comic book by writer Jim Starlin, and artists George Perez, and Ron Lim that inspired the finished film. And there’s an amazing payoff to a joke from Guardians of the Galaxy Vol. 2 that we didn’t even know was left dangling all these movies later. How many of them did you spot?

Of course, there are more out there. Which one is your favorite? Which ones did we miss? Let us know in the comments section below. Also be aware that this post has plenty of SPOILERS about the film. We don’t ruin the ending or anything but if you don’t want to know some of the stuff that happens, this is not the article for you. Avengers: Infinity War is in theaters now.
