Re: 1st image of David Bradley as William Hartnell
I'm not even sure he'd need a wig ... a different hairstyle might be enough. Along with a bit of makeup.
I don't get where that fellow thinks Bradley is a dead wringer for Hartnell. In those park shots he doesn't look a thing like him. Where I come from, that's called, "might be mistaken for the fellow on dark, foggy night by a witness with no corrective lenses and severe myopia."
I dunno, I can see it. The proper hair and clothes will likely help a lot.
"The way I see it, every life is a pile of good things and bad things. The good things don't always soften the bad things. But vice versa, the bad things don't necessarily spoil the good things or make them unimportant."
