Sunstroke is a 2014 Russian drama film directed, produced and written by Nikita Mikhalkov, starring Martinsh Kalita and Viktoriya Solovyova. It is set after the collapse of the Russian Empire during the Red Terror in 1920, with flashbacks to 1907, and is loosely based on the story "Sunstroke" and the book Cursed Days by Nobel Prize-winning Russian writer Ivan Bunin.
The film was selected as the Russian entry for the Best Foreign Language Film at the 88th Academy Awards, but it was not nominated.
