Defence of Sevastopol (Russian: Оборона Севастополя, or Воскресший Севастополь) is a 1911 historical war film about the Siege of Sevastopol during the Crimean War and one of the most important films in the history of Russian cinema and cinema in general. It was the first feature film made in the Russian Empire and it premiered on 26 October at the Livadia Palace of Tsar Nicolas II. It was also the first film in the world recorded using two cameras. The film was also notable for using special "sound effects" (gun and cannon fire) and for using the actual war veterans as consultants.
