Reconstitution (1970 film): Reconstitution (, tr.  "Anaparastasi") is a 1970 Greek dramatic black and white independent underground art film directed by Theo Angelopoulos.  It is the director's first feature film.  While based on true events, it transcends them to recall the ancient myths of the Atrides and Clytemnestra.

Prometheia: The Prometheia (Ancient Greek: Προμήθεια ) is a trilogy of plays about the titan Prometheus.  It was attributed in Antiquity to the 5th-century BC Greek tragedian Aeschylus.  Though an Alexandrian catalogue of Aeschylean play titles designates the trilogy "Hoi Prometheis" ("the Prometheuses"), in modern scholarship the trilogy has been designated the "Prometheia" to mirror the title of Aeschylus' only extant trilogy, the "Oresteia".  Unlike the "Oresteia", only one play from this trilogy—"Prometheus Bound"—survives.  Inasmuch as the authorship of "Prometheus Bound" continues to be debated, the very existence of a Prometheus trilogy is uncertain.  To the extent that modern scholars postulate the existence of such a trilogy by a single author, the consensus holds that it comprised "Prometheus Bound", "Prometheus Unbound", and "Prometheus the Fire-Bringer", in that order.

Tony Harrison: Tony Harrison (born 30 April 1937) is an English poet, translator and playwright.  He was born in Leeds and he received his education in Classics from Leeds Grammar School and Leeds University.  He is one of Britain's foremost verse writers and many of his works have been performed at the Royal National Theatre.  He is noted for controversial works such as the poem "V", as well as his versions of dramatic works: from ancient Greek such as the tragedies "Oresteia" and "Lysistrata", from French Molière's "The Misanthrope", from Middle English "The Mysteries".  He is also noted for his outspoken views, particularly those on the Iraq War.  In 2015, he was honoured with the David Cohen Prize in recognition for his body of work.

Oresteia: The Oresteia (Ancient Greek: Ὀρέστεια ) is a trilogy of Greek tragedies written by Aeschylus concerning the murder of Agamemnon by Clytaemnestra, the murder of Clytaemnestra by Orestes, the trial of Orestes, the end of the curse on the House of Atreus and pacification of the Erinyes.  The trilogy—consisting of "Agamemnon" (Ἀγαμέμνων ), "The Libation Bearers" (Χοηφóρoι ), and "The Eumenides" (Εὐμενίδες )—also shows how the Greek gods interacted with the characters and influenced their decisions pertaining to events and disputes.  The only extant example of an ancient Greek theatre trilogy, the "Oresteia" won first prize at the Dionysia festival in 458 BC.  Many consider the "Oresteia" to be Aeschylus' finest work.  The principal themes of the trilogy include the contrast between revenge and justice, as well as the transition from personal vendetta to organized litigation.  "Orestia" originally included a satyr play, "Proteus" (Πρωτεύς ), following the tragic trilogy, but all except a single line of "Proteus" has been lost.

Dramatic structure: Dramatic structure (also called Freytag's pyramid) is the structure of a dramatic work such as a play or film.

He has written poetry in ancient Greek and Latin, and was commissioned to compose odes in ancient Greek for the 2004 and 2012 Olympic Games (the latter commissioned by Mayor of London Boris Johnson).  In 2013 he was awarded a Research Fellowship by the British Academy to investigate the way music interacted with poetic texts in ancient Greece.

Sweet Bunch: Sweet Bunch (Greek: "Γλυκιά Συμμορία" , tr.  "Glykia Symmoria") is a 1983 Greek dramatic experimental independent underground art film directed by Nikos Nikolaidis.  The film, produced by Vergeti Brothers and the Greek Film Center, is the second part of the "Years of Cholera" trilogy beginning with "The Wretches Are Still Singing" (1979) and ending with "The Loser Takes It All" (2002) which deals with the last decades of the twentieth century.  The original Greek title directly references the Greek title of the 1969 Sam Peckinpah film "The Wild Bunch" (Greek: "Άγρια Συμμορία" , tr.  "Agria Symmoria").  The film uses as background music the 1958 song "Sugartime" written by Charlie Phillips and Odis Echols as well as the 1940 song "Sweet Mara" (Greek: «Γλυκιά Μαράτα,» tr.  "Glykia Marata" ) composed by Leo Rapitis to lyrics by Kostas Kofiniotis which was performed by Kakia Mendri.  It was distributed by the Greek Film Center in Greece and by Restless Wind abroad.

The film has an elaborate yet simple script of strongly contrasting moods.  The film's dialogue contains excerpts taken from published works authored by Daphne du Maurier, Philip K. Dick, Raymond Chandler, and Herman Raucher.  It received the Best Director Award and the Greek National Ministry of Culture Award at the Thessaloniki Festival of Greek Cinema in October 1987, where Dinos Katsouridis also won the Best Cinematographer Award and Marie-Louise Bartholomew also won the Best Art Director Award.
