Pistol dueling in print and energetic postings of applause accompanied the Facebook premier of Theodor Fontane's Effi Briest, which organizers said was the first live staging of a play on the social networking site.

Fontane's classic work, first published as a serial novel in 1894, was specially adapted to be performed on the Maxim Gorki Theater's online Facebook stage on Monday.

The play used status updates, photo uploads and wall postings from characters to relate protagonist Effi Briest's descent into disrepute.

We were really pleased to try something new and innovative, and have learned a lot about how we can use the internet for our productions, a spokeswoman for the theater told Reuters.

Audience participation was encouraged and viewers were asked to help out with a number of tasks, including voting for wedding dresses and posting their contributions to a love letter.

But any ill-timed posts of written coughing fits from audience members were reproached with messages of silence in the theater, please from the moderator and narrator, Theo von Tain, or Theodor Fontane.

At least 1,200 people registered themselves with the production's Facebook group, enabling them to participate in the production, before admittance to the stage was closed at 8 p.m., but organizers said more may have watched online.

We had a large group of people watching and they joined in as we thought they would. They were really attentive but also well-behaved and were quiet when we asked them to be, the spokeswoman said.

The theater would consider staging more plays on Facebook in the future, she said.

Facebook can't replace the stage, but it offers some really interesting opportunities to perform theater online, she said.

The project was arranged to complement a more traditional stage production of Effi Briest, which will premier at the real theater on Saturday.
