Other than a few parts I wasn't aware of for Sydow, plus Serkis as a motion capture model, I haven't seen a single one of these people in anything. That will help me with with getting back into the GFFA. I've been gone a very long time.
From what I've read, they seemed to pick actors respected by their peers, so I expect some solid work. Going by Abrams' ability to get deep performances from his crew, as well as picking out great ones to begin with, I'm not worried abut anything other than story and whatever Serkis will be doing.
Still somewhat optimistic. I'm a huge fan of Abrams' work, but he seems to have all manner of advisers and management whispering in his ear this time out.
Probably related; I nearly watched Star Wars77 this week. Nearly. ;-) Would have been the first time in 10 years.
