Now i know these things might be misleading...but looking at presumed actor portraits and posters side by side:
Celebrimbor seems to be played by a much older actor than i had imagined! Especially considering he Is younger than Galadriel!
On the presumed hobbit girls May and Tyra: both are lightskinned european actresses, i doubt they will be Hamsoms and Coras children if these are played by Lenny Henry and Maxine Cunliffe, two dark skinned actors.
The Meteor-man has very dark hands, somehow i doubt those are Daniel Weymans!
I find it thrilling Eira, Durin's Queen will be played by a dark skinned actress, so she will possibly a princess of the blacklocks! However then she cant be the Mother of the younger Durin as both presumed Durin actors are european looking guys.
Another thing i realized: almost all presumed Numenorean actors are very european looking people, except for Cynthia Addai-Robinson of whom some people believe she will play Asta/Miriel, her supposed father Palantir/Sarador is who people believe Geoff Morell!
Either she doesn't play the part or i wonder if they do something to her ancestry like have her mother be from Harad.
I know, angle and light on those posters might give wrong impressions, but still..
