This movie comprises Caesar & Cleopatra, followed by Anthony & Cleopatra. There is no crossover between the two, they might have been filmed separately.
I gave Cleo 4 stars, only because 5 would be a little to much. The casting of Octavian / Augustus as a golden haired gay boy was absurd; but, fortunately the only real fault in the film.
The historical context is a bit thin, but not so that it spoils the show.
Basically a good movie.
