See, I have a problem with this thought process. There is a place for some of it, Thingol, for example, but Rog is never mentioned as overly tall. Jon Bernthal doesn't need to be tall to be imposing, just look at someone like Tom Hardy (who I believe is 5'9") playing Bane. Still imposing, still impressive, even against 6' Christian Bale. Things like height and hair color can be worked around. I would take a more talented actor who we have to frame differently or put a wig on, over an inferior actor because their physical characteristics match up.In the case of height, the Hosts generally go for taller individuals since Elves are supposed to be tall and it would save on camera effects to make someone look tall. Last season (I can’t really say last year since it’s almost two years since that season), Conan Stevens (Boldog) was partially chosen for his height since he’s supposed to be the biggest Orc around.
To give an example, I’m not sure Jon Bernthal is imposing enough to be Rhogrin at 5’10”.
Sorry, but I do not consider Ridley anywhere near the talent of Bale. Yes, she's been the "star" of the Star Wars films, but I'm not that impressed with her abilities, in what I've seen.This seems to be the case; I remember back in Season 2 when Christian Bale won the vote for Dragluin and the Hosts vetoed that because it was a famous actor in a relatively minor role, which they referred to as an overcast role; they thought it was wasteful. Something similar happened this year with Daisy Ridley as Meril, though the Hosts didn’t veto this time.
