I have both the 2-disc DVD that was packed with extras, and the BluRay that doesn't have very much beyond deleted scenes and a theatrical trailer. Even if the special features from the DVD are all but omitted, the BR is well worth getting, as the sound quality, clarity and punch in DTS-HD is AMAZING! Seriously, it's the best sound I've heard on ANY DVD/BR, and it will probably never be eclipsed. The movie did win an Academy Award for the soundtrack.
