Avengers: Infinity War is the culmination of the entire Marvel Cinematic Universe as started in May of 2008 with the release of Iron Man 1, and it really is an unprecedented culmination of a series of films interlinked together, which at the time had never been done before. And for us the important thing is making it all come together. We know they're gonna face Thanos; we've been setting that up since Avengers 1. How do you do that in a way that is unexpected, that pits the Avengers against somebody who is more powerful than anyone they've faced, and yet make them completely unprepared to face them? Well, tear them apart, which is why we did Civil War before Infinity War… Thanos shows us why he's the biggest, the best, the baddest villain that we've ever had, and the most frightening villain that the Avengers have ever faced.
