I have no idea what I’m doing, so this likely isn’t up to the standards around here. Regardless, below you’ll find an official 5.1 mix of the international version of the second Dark Phoenix trailer. Note that this trailer is quite different from the one posted on YouTube. No official mix of the domestic YouTube version is currently available (to my knowledge).
Edit: Domestic YouTube version by Jonathan now available. See below.
Edit 2: Updated the link to include full size 1080p version.
