This track is dominated by Russell Crowe. Poor Sir Ridley manages to squeeze some words in now and again but this track belongs to Russell and what a great commentary it is too.
Russell is funny,smart,charistmatic and loves pointing out mistakes in the film (much to Ridleys annoyance i think who keeps getting the chat track as far away from glitches as possible.)
This commentary is worth the purchase of the DVD set on its own. Highly recommended

Very engaging and worth the while. In fact, I thought all the related material on the other discs was intersting as well. The story boarding demo was really, really cool. The guy that demos this is so talented and gives the best explaination on why it is important to making movies. Normally, I skip the production design and costume featurettes but this time they were very entertaining and well done.
