The cast of 'Inferno' is kind of staggering when you think about it, because it’s Dante himself, as a character, meeting all these damned souls. Virgil is the obvious lynchpin – he’s the guide, the voice of classical reason leading this medieval Christian poet through hell. He’s constantly explaining the layout and the logic of divine punishment, which is essential, but for me he sometimes feels more like a brilliant tour guide than a fully fleshed person. That’s probably intentional, given his role.
Then you have Beatrice, who’s barely in 'Inferno' at all, just mentioned as the inspiration waiting up in heaven. But her absence is a massive driver for the whole journey. The characters Dante meets are the real show, though. Francesca da Rimini and Paolo, forever stuck together in the circle of the lustful, are probably the most famous. Their story is so tragically human, it’s easy to forget they’re in hell. Then there’s Farinata degli Uberti in the circle of heretics, standing tall and proud even in his burning tomb – that guy has more dignity than most living people I know. And of course, Satan himself, stuck waist-deep in ice at the very bottom, a silent, monstrous ending to the descent.
