Disc one includes a Big Brainstorming writers audio commentary hosted by DVD producer Pete Vantrella with contributors Anne Spielberg and Gary Ross. The commentary is unique in the sense that it’s not entirely contributed to in ‘real time.’ The commentary includes old recordings taped by the two writers when they were penning their ideas. It just so happened that Spielberg recorded many of these "get togethers" and now we can here snippets of them. They are edited down to include highlights but they are presented in the original order so you can get an idea of the order of the construction of the film with collaborative writing. You can listen to this commentary with the theatrical version only.
