It's not a "real" trailer in that there is no movie attached to it. However, it's more than just a fan-made film, real Hollywood types were involved (on screen and off), making it a sort of "pitch" for a new Mortal Kombat film.

I'll say this: looks good enough to make me forget about Annihilation.

Yeh, I know "Jackson" is Michael Jai White (from Dark Knight, Spawn, etc). Looks rated R, it's about time. You can't make Mortal Kombat PG-13, it's like making a movie based on Wolverine that's PG-13...oh wait...

I'll see it. and yes, enough to make me forget Annihilation too.
