The character Igor Dmitriev played in "Hamlet" was summoned by what king to distract the prince from his apparent madness?
Igor Dmitriev Igor Borisovich Dmitriev (Russian: И́горь Бори́сович Дми́триев ) (May 29, 1927 – January 26, 2008) was a Russian film and theater actor who specialized in playing aristocratic characters in costume productions (e.g., Rosencrantz in Grigori Kozintsev's "Hamlet").
Sergei Petrovich Trubetskoy Prince Sergei Petrovich Trubetskoy (Russian: Серге́й Петро́вич Трубецко́й ; 29 August 1790 – 22 November 1860) was one of the organizers of the Decembrist movement. Close to Nikita Mikhailovich Muravyov in his views, he was declared the group's leader on the eve of the December 26 uprising in 1825 but failed to appear, and instead sought refuge in the Austrian embassy.
