A flurry of haymakers in the form of boxing movie clichés, "Southpaw" was conceived as a loose remake of "The Champ" — Wallace Beery in 1931, Jon Voight in 1979 — and tailored for Marshall Mathers, also known as Eminem. The rage-iest rap star on the planet took the initial meetings with director Antoine Fuqua and screenwriter Kurt Sutter. Eminem eventually bowed out, affording Fuqua ("Training Day," "The Equalizer") and Sutter ("The Shield," "Sons of Anarchy") the leeway to rework the project for Jake Gyllenhaal.
