What always was fascinating to me is the fact that Rudolf was really like his mother, he had all her ways of thinking and had himself a deal of 'odd habbits', like his mother, and both they were fascinated by the idea of death.
A miniseries would be great, following the reign of Franz from the Revolt in 1848 up to his death, or the death of Elisabeth. Also a dramatic series, like the Tudors, would be great to see - if it would have some historical accuracy - or even a documentary series on the Habsburg reign(like Russia: Land of the Tsars)
