If you were wondering whether Marvel could make a super team-up bigger than The Avengers, the new trailer for Avengers: Infinity War suggests that the answer is a firm yes.

Virtually every hero in the Marvel Cinematic Universe makes an appearance. Seriously: If you’re watching and you haven’t seen your favorite character yet, just give it another few seconds. The trailer also highlights Thanos (Josh Brolin), the purple villain who made his first appearance in an Avengers post-credits sequence — it looks like he’s finally getting out of his big, dumb space chair.
