I think the difference in opinion between Dinklage and Williams arises because Dinklage thinks there's something wrong with him for being a dwarf, it may not even be a conscious thought, just a sense of shame. Williams doesn't think there's anything wrong with him for being a dwarf, if he thinks about it much at all it's probably just to be annoyed at being short, but he's certainly not ashamed. Some of that difference is probably generational, Dinklage is older, it was harder to be different in the time he grew up in. Not that it's gotten markedly easier, but it's gotten a bit easier, probably enough to matter.

I have so much empathy for anyone who has aphasia. I've had worsening aphasia for many years, probably stemming from a fairly severe TBI that I had when I was 20 (I'm 42 now), I cracked my skull, I was in a coma for several days. It is so incredibly frustrating to grasp for a word that you know that you know, only to find that you can't produce it (you can feel it's there, it's like it's right on the tip of your tongue, but instead of that happening occasionally, it happens all the time). My friends are used to me describing what I mean, or occasionally looking things up on my phone, but I hate doing it when I generally know the perfect word for every occasion. I had an enormous vocabulary, and when my brain cooperates I still do, it just cooperates less and less these days. Aphasia is just awful, I honestly would not wish it on my worst enemy.

Or at least faking forests with potted plants and other set work (this is actually done quite a bit in movies and allows for more control of the visual appearance and lighting). Making them entirely CGI sounds awful.
