Directed by Scott Zigler, the Tony-winning Best Play will officially open Jan. 3 and play a limited engagement through Feb. 3.

A.R.T. company members Will LeBow (Donnie Darko, "Dr. Katz, Professional Therapist"), Karen MacDonald (No Exit, Donnie Darko) and John Kuntz (Mr. Marmalade, Starfuckers) star as, respectively, Niels Bohr, Margrethe Bohr and Werner Heisenberg.

Set in 1941, Copenhagen centers on "German physicist Werner Heisenberg [who] traveled to Copenhagen to meet his Danish counterpart, Niels Bohr. Old friends and colleagues, now they found themselves on opposite sides in a world war, and embroiled in a race to create the atom bomb." The play imagines that encounter.

The design team includes David Reynoso (set and costume), Kenneth Helvig (lighting) and David Remedios (sound).

Copenhagen won 2000 Tony Awards for Best Play, Best Director of a Play (Michael Blakemore) and Best Featured Actress in a Play (Blair Brown). The A.R.T. season will continue with William Shakespeare's Julius Caesar (Feb. 9-March 22, 2008), Pieter-Dirk Uys' Elections and Erections — A Chronicle of Fear & Fun (April 2-May 4, 2008) and Stephen Greenblatt and Charles Mee's Cardenio (May 10-June 1, 2008).

Tickets to shows at A.R.T. at the Loeb Drama Center in Harvard Square, 64 Brattle Street in Cambridge, MA, are available by calling (617) 547-8300 or online at amrep.org.
