Tech Rehearsal of Michael Frayn's play, Copenhagen. Feb. 4, 2017

Joel Sandel and Celeste Roberts, waiting to begin

Celeste thinks about becoming Margrethe Bohr

And Joel who will soon be Niels Bohr

Add Philip Hays, Werner Heisenberg. The three hash out some blocking details.

Turn on the lights. The show is about to begin.

"But why?" ask Margrethe. "Why did he come to Copenhagen?" The ghosts try to reconstruct the past.

Bohr: "I doubt if he ever really knew, himself."

Even the ghost of Heisenberg seems unsure.

Margrethe: "Something alien about him, even then."

Celeste searches out the mind of Margrethe.

Joel sinks into the frustration of Bohr.

Heisenberg with the (drybrush) ghosts of Bohr and Margrethe

Margrethe mediates ...

... while her husband drives home a point.

Is Heisenberg one step ahead, or one step behind?

Margrethe will not suffer fools.

The three ghosts circle and parry.

The Bohrs and the spectral ghost of Heisenberg

Trying to hash it out

Margrethe and Niels

Gemutlichkeit ... as it was in the past, for a moment.

Bohr and Heisenberg sparring

Am I looking at Margrethe or Celeste in this instant?

A worried Bohr

An uncertain Heisenberg

Bohr with ghosts

... and the three of them orbit one another.
