For a while, it looked like Eminem was going to star in the boxing flick Southpaw. But Shady ultimately passed, and the title role went to Jake Gyllenhaal.

However, Em is still involved with the Antoine Fuqua movie. He has at least one new song in it, and you can hear a piece of that in the brand new trailer for Southpaw. The track -- which we're thinking is going to be called 'Phenomenal' -- comes on toward the end of the clip.

Eminem isn't the film's only Hip Hop connection; 50 Cent and Rita Ora both have supporting roles. Southpaw hits theaters on July 31.
