As was announced in 2010, Eminem was supposed to star in the boxing film "Southpaw," written by "Sons Of Anarchy" creator Kurt Sutter. For whatever reason, that didn't pan out, but the film (now complete) will still feature a little Marshall in the form of a new track. The trailer, released today, features a snippet.
The film now stars Jake Gyllenhaal, Rachel McAdams and 50 Cent, and was directed by "Training Day" director Antoine Fuqua. Em's vocals kick off around the two minute mark, and sound angry as ever over a somewhat dubsteppy instrumental. No word yet if this will pop up on a new album, or if it's just a soundtrack exclusive.
