Theodoros "Theo" Angelopoulos was a Greek filmmaker, screenwriter and film producer. He dominated the Greek art film industry from 1975 on and Angelopoulos was one of the most influential and widely respected filmmakers in the world. He started making films in 1967. In the 1970s he made a series of political films about modern Greece.

Theodoros Angelopoulos was born in Athens on 27 April 1935. His father Spyros hailed from the town of Ampeliona, Messenia in the Peloponnese. During the Greek Civil War, his father was taken hostage and returned when Angelopoulos was 9 years old; according to the director, the absence of his father and looking for him among the dead bodies (during the "Dekemvriana" in Athens) had a great impact on his cinematography. He studied law at the National and Kapodistrian University of Athens, but after his military service went to Paris to attend the Sorbonne. He soon dropped out to study film at the Institut des hautes études cinématographiques (IDHEC) before returning to Greece. There, he worked as a journalist and film critic. Angelopoulos began making films after the 1967 coup that began the Regime of the Colonels. He made his first short film in 1968 and in the 1970s he began making a series of political feature films about modern Greece: Days of '36 (Meres Tou 36, 1972), The Travelling Players (O Thiassos, 1975) and The Hunters (I Kynighoi, 1977). In 1978, he was a member of the jury at the 28th Berlin International Film Festival.

Angelopoulos died late on Tuesday, 24 January 2012, several hours after being involved in a crash while shooting his latest film, The Other Sea in Athens. On that evening, the filmmaker had been with his crew in the area of Drapetsona, near Piraeus when he was hit by a motorcycle ridden by an off-duty police officer. The crash occurred when Angelopoulos, 76, attempted to cross a busy road. He was taken to a hospital, where he was treated in an intensive care unit but succumbed to his serious injuries several hours later. Prior to his death he suffered at least one heart attack. His funeral was a public expense, on 27 January at the First Cemetery of Athens.
