I've just discovered that back in January 2020, I did an analysis elsewhere of the initial 15 cast members announced for "Rings of Power". That inspired me to put together a list of all the cast members announced so far:
Confirmed roles:
Unknown Roles:
- Joseph Mawle - originally announced as "Oren", the main antagonist
- Tom Budge
Unidentified posters:
(ie, characters who got a preview poster, but for which no name has yet been confirmed)
I'll try to keep this updated as more announcements come out (at least for the next, uh, two months, until the series airs).
