Marvel has two 30 second trailers for the Super Bowl.
The first one is for Captain Marvel:
It’s mostly more of what we’ve already seen and they play up her catch phrase “Higher, Further, Faster.”
Captain Marvel comes out on March 8.
The second trailer was for Avengers: End Game:
We see the remaining Avengers regrouping and dealing with the loss of their friends. Again, not much is shown in the 30 second spot, other than the idea that time has passed since the last film.
Avengers: End Game will hit theaters on April 26, 2019.
