If you mean actors with serious stage cred (in the tradition of Christopher Plummer and Patrick Stewart), I'd look at those who have won and/or been nominated for TONYs and/or Olivier Awards. A few names that come to mind would be Andrew Garfield, Condola Rashad, Michael Cera, Lupita Nyong'o, Ruth Wilson, and Carey Mulligan. You may or may not like them, but I think they're generally among those considered to be high level dramatic actors, most of whom move between stage, movies, and television/streaming projects.
