There seems to be a misunderstanding, as Mikhail Gorbachev is not known as a film actor. He was a prominent Soviet politician, serving as the General Secretary of the Communist Party of the Soviet Union from 1985 to 1991 and the last leader of the Soviet Union. Gorbachev is renowned for his key role in ending the Cold War and implementing significant reforms such as glasnost and perestroika. His leadership contributed to the dissolution of the Soviet Union in 1991.
