From everything I’ve read, it does seem like it was quite difficult to get on with William Hartnell, but there were those that managed it.

That’s fine really, it’s the same way with people like Gene Roddenberry and William Shatner. In-universe, there are the legends of the guy that created Star Trek and the guy who played James T. Kirk, but if you dig a little deeper and talk to people that know the real people, new, more realistic things emerge that you might not particularly want to know because they destroy that illusion.

It’s like those who don’t like to see on-set photos of the Tardis being put together because it exposes it as just a wooden box with a load of wiring, even though it doesn’t particularly bother me.

I’ve come to feel that, within reason, whatever the actor was really like, you do at least know the character and that’s really what you’re a fan of.
