I'll admit i'm not a huge fan of audio commentaries as I find most of them pretty boring. When it's producers & directors, they tend to ramble sometimes wheras cast members, as long as they're in the same room, are very enjoyable. Most entertaining ones: Any with Kurt Russell! He has the most fun watching his movies and laughs his a** off which is very infectious. Escape From NY, The Thing, Big Trouble but his best is...Used Cars! Every time i take it out to watch, it's always with the commentary. Very funny! Re-Animator-The movie itself was so goofy you had to laugh but all the cast members are on the track and they have a great time. Most informative: I'll go with Carpenter's. He gets very detail oriented without being boring. Any others?
