A few people have asked and I didn't see anyone answer, but for those of you wondering about the bonus disc that came with the Walmart set, it's a feature on the Lizard that's about 20 minutes long. A little of the content is also in the 90-minute making-of documentary, as well as from one or two of the featurettes that came out before the movie was released in the summer, but they mostly talk about the character and whatnot. Pretty typical stuff. I liked it, but then again, the Lizard is my favourite villain, so I'm biased.
Personally, I thought the most interesting things on the bonus disc were some additional behind-the-scenes footage (eg. it seems like in the library fight scene, Peter tries to appeal to Connors' human self after the fight ends), including a very short clip of Annie Parisse as Martha. Unfortunately, the clip lasts for about three seconds, but it was still neat to see. I wish the disc had included some of the Connors deleted scenes that were mentioned in interviews or shown in-part in other things, but not included on the deleted scenes reel :|
