Playwrights Mikhail Ugarov and Elena Gremina were unhappy with the state of Russian theatre in the early 2000s. Then they went to London. There, “they learned about documentary theater — the use of interviews, oral history and journalistic sources to create works for the stage. Ms. Gremina and Mr. Ugarov embraced the technique, brought it to Moscow and in 2002 established Teatr.doc, a theater company that presented shockingly raw accounts of life in post-Soviet Russia.”
