Definitely have to be my favourites. I've never seen an ancient one that could be on any real sort of favourites list, unfortunately, except possibly Passion of the Christ - simply due to the effort going in to make as few historical concessions as possible. The 1963 Liz Taylor Cleopatra will always be some sort of favourite.
There was a miniseries on TV about 3 years ago about the fall of the Roman republic, which I thought was great. Can't remember the name, though. It was around a time when there were a few ones being made (one of which had a cute blonde Aussie actor); all of which were shit except the one I'm thinking of... Things like Troy and Gladiator never really do it for me.
