I’m a big fan of Tinto and Caligula, so I was giddy as a schoolboy when I heard the news. The theatrical version is such a mess, so it’s understandable why audiences have felt so alienated by it. It’s like someone trying to read you a poem while a big band plays loudly in the foreground. I imagine that in addition to the deleted content, the scenes we’ve been seeing for years will have a whole different meaning now.
Ideally, apart from a theatrical re-release, the restored cut ought to be presented along with the theatrical one, since the current releases don’t have the original audio.
