Selected home-video releases:The Last King of ScotlandThe soft-spoken Forest Whitaker came out of his shell in an explosive way, winning the best-actor Academy Award for his magnetic and frightening performance as Ugandan dictator Idi Amin, who remains a perversely respected figure among the subjects he tormented. The film presents a fictionalised personal relationship as Amin is seen through the eyes of an adventurous Scottish doctor (James McAvoy), initially enticed by the ruler’s forceful charm, later a horrified witness and victim to his brutality.

The DVD has seven deleted scenes with commentary from director Kevin Macdonald, who also offers commentary for the full film. A behind-the-scenes segment features Whitaker discussing the extensive research and preparation it took to play Amin, and the disc has a documentary on Amin’s rise to power and how the filmmakers went about re-creating his reign.

Jeremy Piven plays the title role, “Aces” Israel, a magician placed in protective custody after he agrees to testify for the FBI against the mob, with Affleck, Alicia Keys and a huge roster of other rogues trying to cash in on the $1 million mob contract placed on Aces’ head. The disc has deleted scenes, outtakes and an alternate ending, a featurette on stunts and special effects and a segment on writer-director Joe Carnahan, who also teams with his editor and some of the actors on two commentary tracks.

(Universal)Freedom WritersHilary Swank stars in a feel-good classroom drama based on the true story of idealistic teacher Erin Gruwell, who inspired her students at a violent, racially divided school to express themselves with pen and paper. Swank’s Gruwell battles skeptical school bureaucrats, her own doubting family and entrenched biases among the youths, who gradually bring out their inner poets as they find kinship by sharing stories of their own harsh lives.

Along with a handful of deleted scenes, the DVD has segments on Gruwell’s real-life story and the many students who benefited from her writing program. Swank joins writer-director Richard LaGravenese for commentary. Notes on a ScandalPast Oscar winners Judi Dench and Cate Blanchett each scored fresh nominations for this dark drama about a flighty new teacher and the twisted veteran educator who preys on her young colleague.
