Second trailer released. Oh, and as mentioned in the intro to the trailer, the trailer spoils Avengers: Endgame. So, if you haven't seen Endgame, do not watch the trailer.
EDIT:
Oh, and tickets are on sale. The local theater that I prefer doesn't have them up yet, but others around me do. Odd thing about the tickets are that the movie opens on a Tuesday (due to July 4th being that Thursday), and from what I can see, the early screenings are actual midnight showings again. I haven't had to do one of those in years!
