I'm kinda confused. There are 2 versions which are considered good. The 2-disc version with extras and the new superbit without them. How do they compare? I'm really interested in the great, powerful 5.1 mix plus decent picture but I also would like to know more about the movie (Peter O'Toole gives probably the best performance of all time here) and Lawrence, the historic person. So it narrows us to basically 2 very important questions: 1 - Is the pircture/sound THAT better on Superbit to sacrifice the extras? 2 - Are the extras worthy?
