The Mortal Kombat Rebirth trailer (see below) that hit the Internet yesterday is not a trailer. It's not a trailer for a game or a movie. It's a pitch for a movie.
According to a tweet from Seven-of-Nine (7 of 9 even) actor Jeri Ryan:
"It's not a game trailer. Actually was made for the director to sell WB on his vision for a reimagined MK film."
She continues, "More MK FAQs: I did it as a favor to a friend. No idea yet what WB's reaction to it was. And I'm not sure how you can contact WB..."
