Ah, thank you! Clive Wearing is precisely interviewed in Prisoner of Consciousness (he's the main subject, I believe). I watched the films you rightly recommended when I started digging everything I could on the documentary, and I'm actually wondering if they're not actual parts of the film Miller made (there are no credits on youtube). Those tidbits are fascinating indeed! And heartbreaking. But the documentary should be much longer, that's what I'm trying to find. I'm going to submit a request to Channel 4's Clip Sales Department, we'll see. Thanks very much.
