I'd agree with B666, it is a historical film with h/c add ins. I think the fact that the director and writer did not know that the producer, Guccione, filmed the h/c and added them to the film thereby totally messing up the vision of the director and writer does not make it a h/c film.
If the producer of any film added h/c scenes to any film (love actually, Muppet's Christmas carol, anything) it is simply a film that has h/c added to it.
the problem was what it did to the film. It really screwed with the editing and the story telling. The whole look of the film was striking, I think you get a strong idea of how alien Caligula's Rome was...the past is really another country
What they did is
much stranger/pornographic than anything in the film.
I've always found it strange that PH could be so stupid as to add h/c scenes.
I liked Bob's photographs. i think he did an amazing job a producing some really erotic photographs. I don't know why he totally screwed Brass's vision (and Caligula is probably his finest work, definitely his most expensive).
More than that, it killed PH's film activities....no mainstream talent, actor, director, writer, would work for them. No one wanted to be linked to h/c/ porn.
it's a shame because Caligula was an intelligent film that might have led to something interesting.
Considering the financial problems PH had/have this is very short sighted.
a really stupid business decision in my opinion.
