Girlfight contains a choice between widescreen and full-screen transfers on opposite sides of the disc. The 1.85:1 widescreen anamorphic transfer shines with radiant colors. But a slight level of grain does exist throughout the film, which is mildly distracting. It's an impressive visual transfer overall, but it falls a bit short of being pristine. The 5.1 channel Dolby Digital transfer succeeds wonderfully during the boxing matches. Each blow resounds strongly in the side and rear speakers, and the music keeps the action tense and exciting. Even though much of the movie involves dialogue, the powerful piano score is crucial, and the audio track supports the force of the story. This disc also contains a decent 2.0 channel Dolby Surround transfer. Writer/director Karyn Kusama speaks with an understanding of film that is amazing for a first-time director. Her feature-length commentary is a fascinating explanation of the ideological and technical aspects of the movie. Kusama's comments stray from simple explanations of scenes, focusing more on her ideas for the characters. She has sentimental views about boxing and understands its allure, and this really deepens a viewer's understanding of the story. This disc also contains a brief featurette, cast and crew information, and several theatrical trailers. The five-minute featurette is fairly pointless promotional information, but Kusama does provide a few interesting insights. The cast section contains short biographies and selected filmographies for Kusama, executive producer John Sayles, Michelle Rodriguez, Jaime Tirelli, and others. The trailers for Girlfight, Black and White, and Charlie's Angels are presented in nice 1.85:1 widescreen transfers.
