I watched the DVD Ludwig II, it was rather annoying as it had Italian subtitles, but it was the only one available that could be played in Region 1.
It is a dark sort of tale, and the Cuckoo flew over Ludwig's nest twice...............But, I was so impressed with Romy Schneider's portrayal of Elisabeth. What a relief it must have been for her to be able to portray the Empress Elisabeth so much closer to what she would have been, than was portrayed in the sugar sweet trilogy.
Can you imagine a movie made to depict the life of the Empress, true to history, with Romy's daughter playing the young Sissi and, if Romy would still be alive today, her as the older Empress.
