On the DVD Criterion's beautiful restored print of Brute Force is accompanied by a small collection of supporting materials, including a commentary track by longtime film noir experts Alain Silver and James Ursini. They give a good brief on the film's history, such as the disagreements between producer Mark Hellinger and director Jules Dassin on the subject of the movie's use of flashbacks--an approach that would break the claustrophobia of the prison sequences and introduce female characters. Hellinger wanted the backstory, Dassin objected, and the producer won; but the point is definitely arguable. Prison-movie specialist Paul Mason gives a useful 15-minute talk, partly on Brute Force and partly on the genre of prison movies. Criterion's booklet has an excellent essay by critic Michael Atkinson, a vintage 1947 profile of the colorful columnist-turned-producer Hellinger, and an intriguing, bitter exchange of letters between Hellinger and Production Code chief Joseph Breen on the subject of the film's censorship problems. --Robert Horton
