"Caligola" is a 1979 movie with Malcolm McDowell as the title character and this one here is a 5-minute spoof of the movie from 10 years ago. It also lists Gore Vidal as a writer, but I am not sure how accurate this is. The cast, however, is pretty good: some really big names in here such as del Toro, Jovovich, Bateman, Black, Butler and last but not least Helen Mirren, who also starred in the original movie. This parody was done briefly before Mirren won her Oscar for "The Queen". Anyway, lots of obscenity in this little movie, lots of screaming and spectacular costumes (if they wear anything at all). I have not seen the original movie and I am not sure I ever will, but this short film here did not get me too interested I must admit. It's 100% comedy, but I almost never found it funny. Not recommended.
