The Cambridge, MA stage will now offer No Child... (Nov. 24-Dec. 23) and Copenhagen (Jan. 3-Feb. 3, 2008). Both works — which were originally announced to play the season in the reverse order — will perform on A.R.T.'s Loeb Stage.

Hal Brooks directs No Child..., which is written and performed by Nilaja Sun. The work stemmed from the creator's work as a teaching artist at a high school in the Bronx, "where every day the students face huge challenges in simply coming to school." Sun tackles all the roles in the piece transforming from students, teachers and parents to administrators, janitors and security guards.

Scott Zigler stages Michael Frayn's 1941-set Copenhagen, which 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 — to star Will LeBow, Karen MacDonald and John Kuntz — imagines that encounter.

The season at A.R.T. will also offer Donnie Darko (Oct. 27-Nov. 18), 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.
