What projects?
Kit Harrington's last two movies flopped (three, if you count "Eternals") and he's currently a side character on "Industry".
Damn near none of them have anything going on, from the writers on down to the actors. "GOT" was the high light of their careers.
Fred.
I'm not them but they all were clearly losing enthusiasm as the last seasons rolled around and probably wanted out if things weren't going to turn around.
Kit wanted a break from being the snowman just as much as Gandolfini wanted to be James rather than Tony at some point in time.
I agree tho, typecast actors seldom have success outside of their famous roles ie...the Star Trek cast iirc..
