That is what always puzzled me? They had to have had the lions share of the sets and wardrobe already done to make 2 seasons of the show. Hbo at the time was fucking up left and right canceling deadwood and rome, I am betting it had more to do with actors demands for salaries coupled with other expenses ( such as any new sets/costumes) and balancing that with the fact that the show was not bringing in Soprano like numbers ( same with Deadwood). How is Spartacus dealing with the set/ costume money problem CGI?

I know that those shows are not returning but how I would love to see movies of them, like Arrested Development is currently doing.
