London Premiere – 1998
Copenhagen opened in the National Theatre in London and ran for more than 300 performances, starring David Burke as Niels Bohr, Sara Kestelman as Margrethe Bohr, and Matthew Marsh as Werner Heisenberg. It was directed by Michael Blakemore.
"Copenhagen" transferred to the Duchess Theatre in London's West End, where it ran from 8 February 1999, for more than 750 performances. It had a "second" cast when it opened in the West End, who were responsible for performing at least one of the matinee shows each week. The second cast consisted of David Baron as Niels Bohr, Corinna Marlowe as Margarethe Bohr, and William Brand as Werner Heisenberg, and after six months, they replaced the original cast for the rest of the West End run.
Broadway Opening – April 2000
Continuing under the direction of Michael Blakemore, it opened on Broadway at the Royale Theatre on 11 April and ran for 326 performances. Starring Philip Bosco as Bohr, Michael Cumpsty as Heisenberg and Blair Brown as Margrethe, it went on to win the Tony Award for Best Play, along with two others for Best Featured Actress in a Play (Blair Brown), and Best Direction of a Play (Michael Blakemore). But even for its success, Frayn admitted in an article that "A number of commentators expressed misgivings about the whole enterprise ." Several critics noted that it was heavy with scientific dialogue, a little too heavy for the common audience. Though a writer from Physics World hailed it as “brilliant theatre ,” a Charles Spencer, of the Daily Telegraph, wrote, "I felt that my brain was being stretched to breaking point—well beyond breaking point, in fact."
TV Movie – 2002
The play was adapted as a television movie in 2002, with Daniel Craig as Heisenberg, Stephen Rea as Niels Bohr, and Francesca Annis as Margrethe Bohr. The movie substantially cuts down the script of the play, eliminating several recurring themes, and most of the material that established the community of scientists in Copenhagen. It also abandons the abstract staging of the theatrical version in favour of being set in the city of Copenhagen, in Bohr's old house.
The play has been revived at:
