Add-ons to the first 5 discs also include a breakdown , in detail, of the "gladiator" sequence ("Thirteenth!") and Caesars Triumph.
Disc 6 is a special of extras : actors boot camp, sets, wardrobe.
A feature on Roman life (everyday life in the City)- and a picture gallery.
edit: The Roman Life extra is a 30 minute meditation on "were they like us or not?" , a constant theme underlying many debates in the various Forii here. One of the most useful remarks in attempting to achieve a Roman world "mind set" is the constant reminder that (this crucial period of the Triumvirate ) is wholly outside of any Judaeo-Christian moral framework. This is almost platitudinous but it bears repeating.
The rejoinder is , religion was everywhere in daily life and the activities of the state, but "Liberal Morality" as we understand it did not exist. Ok I know its just a tv entertainment , but having listened to Heller and his historical advisors , I dont doubt it is also a sincere attempt to make the place and things as accurate as can be, and a valiant attempt to re-create a different moral universe.
