Eminem was originally reported to be starring in the boxing film when it was announced back in December 2010, but soon dropped out of the project allowing Jake Gyllenhaal to step in for the role.

Based on a boxer fighting his way to the top only for his life to fall apart around him, the star-studded cast also includes Rachel McAdams, Forest Whitaker, Fifty Cent and Rita Ora.

Though fans will have a long wait to hear the track in full, with the release date for Southpaw July, 2015.
