I remember hearing about this a year or two ago, but it was just in the concept stage back then. No one had even been hired to do anything with it at that time.
It certainly looks like Fallout 4From looking over the IMDB, Walton Goggins is only in 4 episodes, same with Kyle McLachlan. So they must not be the protagonists.
That's fine with me. I cannot stand Walton Goggins. It is through no fault of his own. I am sure he is a nice man (bracing myself for when allegations come out about him in the future). But the first role I ever saw him in was on the Shield, where he played a weasely, worm of a toadie attached to the protagonist of Vic. I have never gotten that slimy henchman portrayal out of my head, so that is all I can ever see him as.
Hopefully he is a villain in this, like he was in the recent Tomb Raider movie. He is good at that sort of thing.
