Get ready to fire up your reaction videos, because Marvel Studios is releasing the first Avengers: Infinity War trailer Wednesday.

To whet the appetite, Marvel released a retrospective video looking back at some of its best trailers dating back to 2008's Iron Man, paired with fan reaction videos to those trailers.

"Everything you know, everything you've experienced, everything you've imagined, it has all been leading to this moment," reads the teaser.

If you're feeling impatient, you can read this detailed description of the first Infinity War footage, which screened at D23 in July. Infinity War, a film from the Russo Brothers, is written by Christopher Markus and Stephen McFeely, who penned the three Captain America movies.
