Slumdog Millionaire may have enjoyed its best weekend to date in theaters last weekend -- even after nearly four months in release. And the Academy Award winner's legs are likely to remain steady for several more weeks. That's why analysts were somewhat surprised when Fox announced that Slumdog , whose Oscar wins included best picture, director (Danny Boyle), and adapted screenplay (Simon Beaufoy), would be released on DVD and Blu-ray disc on March 31 -- just four weeks from now. The Blu-ray version, it said, will include a bonus music video. The A.R. Rahman soundtrack won Oscars for best original score and best original song.
