Camelot
I received an advanced copy of the first episode through my company (I work for cable television).
James Purefoy is back. He is essentially playing the same exact character, except that Marc Antony is now a Dark Age warlord.
And the series is basically the same as HBO:Rome, with sex and violence and political intrigue. But now you get some stunning Irish scenery thrown in. (Although, amusingly, Camelot castle is said to be a fortress built by the Romans, another Rome link).
This looks likes another sexy, costume drama piece that adults can enjoy as long as they don't analyze the historical background too seriously. And even if James is playing basically the same character, I admit he is pretty damn good at it.
