Michelle Dockery is most famous for her portrayal of Lady Mary on Downton Abbey. I also loved her as con artist Letty Raines on the very fun show Good Behavior.
I think she’s in that class of people who would not move the needle significantly at the box office, but she costs a lot more than hiring a journeyman stage actor. Unless she happened to get Jodie Comer-level reviews in London first.
Back in 2017, she played Diana (the Faye Dunaway role in the 1976 film) in the 2017 London World Premiere of the stage adaptation of NETWORK, opposite Bryan Cranston.
So many Downton Abbey stars were on Broadway shows though.
