"A tragedy has happened. Gleb Anatolyevich Panfilov has passed," Mark Varshaver said.
Panfilov was hospitalized with a stroke in May, nearly four months after the passing of his wife of 50 years, Inna Churikova.
Varshaver told Sputnik in spring that the filmmaker developed pneumonia. His condition in August was described as satisfactory, although he complained of feeling unwell.
Panfilov is known for a string of mostly historical films that won critical acclaim both at home and in Europe, such as "No Path Through Fire," "Vassa" and "The Romanovs." His 1979 film, "The Theme," won the Golden Bear at a Berlin film festival in 1987.
