No, it's not about ancient, lost Martian civilisations living in underground cities, but a DVD about the work of Bob Zubrin and the exploration of Mars. Very good DVD which unlike some US stuff, isn't all hype and no substance. As a matter of fact, it's very matter of fact and quite to the point about how we should go to Mars and what needs to be done and where we've failed so far. Well worth the money spent ($10)
You should be able to get it in any DVD outlet, but I bought my copy in Big W.
