The bonus features presented on The Blues Brothers Blu-ray have all been seen before on prior DVD releases. For starters there's a theatrical trailer included here along with some Blu-ray functionality with BD-Live. The actual features contained here include a 10 minute piece called "Remembering John", which has some of the people closest to Belushi reminiscing about the man, his work, and how he impacted their lives. "Transposing the Music" is a 15-minute feature including interviews. Finally, "Stories Behind the Making of The Blues Brothers" is a nearly hour-long featurette. "Stories" is basically the be all and end all of what it took to make The Blues Brothers with tons of interviews, footage, and behind the scenes stuff. If you haven't seen it before it's totally worthwhile to watch.
If you can't tell, The Blues Brothers gets very high marks across the board. The film itself is, of course, still as good as it's ever been. The picture quality is definitely an upgrade over what's come before it, and the audio is nothing to sneeze at. The bonus features disappoint in the sense that we've seen them before in prior releases, but they make up for it in quality. If you're a fan of The Blues Brothers you'll want to pick up this release. It's a great addition to that Blu-ray library.
