In the movie, Gyllenhaal plays famous boxer Billy Hope, who loses custody of his daughter after his wife (Rachel McAdams) is shot (not a spoiler, it's in the trailer).
Eminem's music is featured in the trailer ("some new stuff I've been working on," he says on his YouTube page) and he was initially supposed to star in it. The film, directed by Antoine Fuqua, also stars Forrest Whitaker, 50 Cent and...oh snap...Rita Ora. It's out July 31.
