Plot – Spoilers:
An alternate version of Caligula, this here is the extended hardcore version. But this leads to a bizarre situation where the characters switch from speaking English to Italian, mid-scene, probably because the film was originally made in Italian and the edited-out scenes later added to the dubbed English version.

Caligula is kind of infamous for a 23-minute-long scene that features orgies set against violence and food and also some horse cock. There are also violent penetrations of male and female orifices, if that’s of any passing interest to you.
