Comandante

An opportunity frustratingly squandered, but one which still makes for fascinating viewing thanks to Castro's natural charisma. Errol Morris would have nailed it.

The pair make a smug double act, but you can't fault them for charisma.

Fidel is up to everything Stone lobs gently at him, and even replies to the film-maker's rather crass philosophising, of which there is far too much.

Even when he seems less than forthright, Castro rarely fails to come across as a genial, charismatic guy. But that might just be the magic of the movies.
