dalmeny is right that the crucial question when contemplating a re-make of B7 is who would the actors be? I've got some decided preferences. But here's a Blakes 7 question prompted by a follow-up comment by iainjcoleman: "Avon is more or less actor-proof". I guess that we've seen the biggest old ham in the business make a terrific glorious mess of the part, and we love it.
But is there anyone who would actually ruin the role, or is Avon such a wonderful character that any actor could make the part worth watching. Anyone? Mackenzie Crook? David Jason? Orlando Bloom? No, in a way I could see any of them in the role at a pinch.
