Copenhagen

This is the final weekend to catch Copenhagen, a thoughtful exploration of the difficulty of ever truly knowing oneself or others. Presented by Cesear's Forum in a limited engagement, the Tony Award-winning play centers on an actual meeting that took place between the two great physicists, Germany's Werner Heisenberg and Denmark's Niels Bohr, in 1941, in occupied Denmark. The play is presented fictionally, "inside the heads" of three characters, as they relive their memories and speculate on the meaning, and consequences, of their actions. Tonight's performance takes place at 8 in the intimate Kennedy's Down Under, in Playhouse Square. Tickets cost $18, and the performances continue through tomorrow. (Niesel)
