Yeah, it seems to be confirmed, but I’m looking at the above photo/clip, and one thing that strikes me is his upper arm.
In ROTSS there were many scenes with Chiklis as Ben wearing clothes and I noticed the upper arms seemed a bit “sunken” and he looked a little Popeyeish (presumably because the padding in those upper arm areas wasn’t as stiff as the rocky forearms. )
And I’m seeing a similar appearance in that photo.
But if they do use practical effects, I’d assume they’ll use them for brief, static scenes like that.
A big problem with Chiklis’ suits was he moved clumsily - like a man in a heavy suit rather than a powerful cosmic irradiated being.
It’s also possible that that isn’t the final scene and they did that as a pre-vis and/or something just for the fans.
