I got asked about this one on Twitter:
Strictly speaking, it’s drawing from the prequels to the Foundation trilogy, doesn’t it? Which I only vaguely read, and not all of them. But I’m pretty sure that we’re not going to see the Mule in this, unless of course they completely rewrite the timeline. Which would be extremely ironic, in its way. The whole point of Foundation, to me, is how far the story stretches out beyond the scope of any one protagonist.
As to whether it will suck or not? Damifino.
It’s still a shame that Hollywood will never have the courage to adapt The Weapon Shops of Isher and The Weapon Makers.
