I, Claudius, that remarkable combination of comedy and horror, is worth watching (again) for many reasons, but few better than seeing John Hurt do Caligula. Such as in this scene, which only goes to show there’s no profit in reasoning with a lunatic who also happens to hold absolute power.

It’s all a fine production all the way through, but once Caligula is offed, the story loses a bit of its spark. A bit of its insane spark, that is.
