This fall, Denzel Washington's new film, The Equalizer, will hit theatres. Today, the official trailer for the film dropped with a special surprise—a new Eminem song featuring Sia. Though it's just a snippet of the song, it sounds pretty dramatic and fits the trailer nicely. Sia and Em have connected once before this for the MMLP2 bonus track, "Beautiful Pain."

As of right now there is no word on when Em will release the song, but we can only hope it's sooner than later. Watch the trailer above before the film hits theaters this September.
