Can you identify the people in this photograph? (Hint: It's a still from a 2012 National Theatre production of Antigone.)
It's Claire, Karvanista and the Thirteenth Doctor! (a.k.a. Annabel Scholey, Craige Els and Jodie Whittaker).
The male lead, Creon, was played by Christopher Eccleston, and the IMDb says Alfred Enoch (i.e. William Russell's real-life son, and also Harry Potter's Dean Thomas) is, like Els, one of the Greek Chorus.
I've seen clips from this, and Whittaker absolutely holds her own on the stage with Eccleston. The woman can flat-out act, at least if she's given decent writing (cough, Series 11 and 12, cough). I've been poking around, and I think I can subscribe to the National Theatre's streaming service for a month for $13, and I'll probably do just that (and see what else I can binge on while I'm there).
ETA: Or it can straight up be rented for $8. I'll still poke around to see if there's other stuff I want to watch -- Ruth Wilson as Hedda Gabler is tempting, as is "An Evening with Ian McKellan."
