Max von Sydow (, Swedish: [fɔn ˈsy̌ːdɔv] ; born Carl Adolf von Sydow; 10 April 1929 – 8 March 2020) was a Swedish-French actor. He had a 70-year career in European and American cinema, television, and theatre, appearing in more than 150 films and several television series in multiple languages. Capable in roles ranging from stolid, contemplative protagonists to sardonic artists and menacing, often gleeful villains, von Sydow received numerous accolades including honors from the Cannes Film Festival and the Venice Film Festival. He was nominated for two Academy Awards: for Best Actor for Pelle the Conqueror (1987) and for Best Supporting Actor for Extremely Loud and Incredibly Close (2011).

Von Sydow was first noticed internationally for playing the 14th-century knight Antonius Block in Ingmar Bergman's The Seventh Seal (1957), which features iconic scenes of his character challenging Death to a game of chess. He appeared in eleven films directed by Bergman, including Wild Strawberries (1957), The Virgin Spring (1960), Through a Glass Darkly (1961), Winter Light (1963), Shame (1968), and The Touch (1971).

Von Sydow made his American film debut as Jesus Christ in the Biblical epic film The Greatest Story Ever Told (1965) and went on to star in films such as Hawaii (1966), The Exorcist (1973), Three Days of the Condor (1975), Flash Gordon (1980), Conan the Barbarian (1982) and the James Bond adaptation Never Say Never Again (1983). He also appeared in supporting roles in Dune (1984), Hannah and Her Sisters (1986), Awakenings (1990), Minority Report (2002), The Diving Bell and the Butterfly (2007), Shutter Island (2010), Robin Hood (2010), and Star Wars: The Force Awakens (2015). He portrayed the main antagonist Leland Gaunt (The Devil) in the film adaptation of Stephen King's Needful Things (1993). In 2016, he portrayed the Three-eyed Raven in the HBO fantasy series Game of Thrones, for which he was nominated for the Primetime Emmy Award for Outstanding Guest Actor in a Drama Series.

Von Sydow received the Royal Foundation of Sweden's Cultural Award in 1954, was made a Commandeur des Arts et des Lettres in 2005, and was named a Chevalier de la Légion d'honneur on 17 October 2012.
