Sergei Eisenstein (1898-1948) was a Soviet film director, screenwriter, and film theorist, considered one of the most influential pioneers of cinematic language. His fame is inextricably linked to his innovative theory of montage, which he used to generate intellectual and emotional associations in the viewer. His career took off in the 1920s with revolutionary propaganda works such as *Strike* (1925) and his universally recognized masterpiece, *Battleship Potemkin* (1925), celebrated for its masterful Odessa Steps sequence. After *October* (1928), he faced a period of difficulty due to Stalinist political pressure. He found success again with the historical epic *Alexander Nevsky* (1938) and the monumental, unfinished trilogy *Ivan the Terrible* (1944-1946). For these two works, he received the Stalin Prize, the Soviet Union's highest artistic honor. His influence on film direction and theory remains fundamental and is studied worldwide.
