Boxing drama Southpaw has seen more than a few changes both in front of and behind the camera, but director Anton Fuqua has finally solidified the cast list, and Naomie Harris has now jumped aboard.Originally developed as an unofficial follow-up to 8 Mile with Eminem playing a boxer, Southpaw has since evolved into a standalone film, with Jake Gyllenhaal as Billy "The Great" Hope, a left-handed pugilist who wins a big title but suffers a tragedy shortly after. With his life in tatters he must piece everything back together to regain the respect of his young daughter. Sons Of Anarchy creator Kurt Sutter wrote the original script, though Fuqua has reportedly since brought on Equalizer collaborator Richard Wenk to polish it.Though Lupita Nyong’o had been in courted to play one of the main roles, Harris will instead step in as Angela, the social worker who aids Gyllenhaal and his offspring.
