The Italian one is in the original format, but open matte. It was shot for a 1,66:1 aspect ratio.
The sinister cinema is obviously a 1,33 version from a 1,66 or maybe 1,85 source. As it is not open matte it is cropped from the sides. But not that much.
For the moment a fan dub of the RAI version would be the best we can get.
