Ibsenite drama at the national theatre. Instead of holding up their passports, the cast held up an enormous code to scan on the cell phone, perhaps more related to the concerns of the play, rather than the politics of the moment. (As I don't speak the language or carry a pocket device, both were Greek (second aorist) to me. There actually is a way to parse these codes manually, but you have to memorize a series of overlays first, and then work out the sequence.) Also an interesting moment with Torvald's knitting/embroidering tips.
Many notes, but the most interesting moment was the door closing -- entirely unstaged, but unforgettable from my standing-view angle of sight. Long applause from the house after Nora's last line, with house lights at half--peculiar, perhaps a European stage tradition? Then, in the blackout, the actor walked to the nearest exit, lit by the accidental light from outside against the deep red of the carpet, and a click from the modern door behind her. The romantic, progressive theatre of Ibsen, but there is a world elsewhere -- this was just a brief framing of it.
