Between 2006 and 2008 Guy Cassiers concentrated on his Triptiek van de macht – Mefisto for ever, Wolfskers and Atropa. De wraak van de vrede (Atropa. Avenging peace)- about the complex relationships between art, politics and power. He took that theme a step further in a triptych based on Robert Musil’s great novel Der Mann ohne Eigenschaften; The Parallel Action (part I, premièred June 2010), The Mystic Marriage(part II, premièred September 2011) and The Crime (part III, premièred May 2012). Besides the projected image, music also started to play an increasingly important role in Cassiers’ productions, as evidenced by two operas he created in 2009: House of the Sleeping Beauties (music Kris Defoort) and Adam in Ballingschap (Adam in Exile; music Rob Zuidam). He has since staged the complete cycle of Wagner’s Der Ring des Nibelungenin Berlin and Milan (2010-2013).
We have seen evidence of Guy Cassiers’ growing interest in European political history in projects like Bloed & rozen. Het lied van Jeanne en Gilles (Blood & Roses. The Song of Joan and Gilles 2011), about the power and manipulation of the Church, and Duister hart(Dark Heart, 2011) based on Joseph Conrad’s Heart of Darkness about colonial history. With productions like SWCHWRM (2010) Guy Cassiers shows he is also capable of striking a lighter note, which again manifested itself in his appearance in Middenin de nacht (In the Middle of the Night), a production in January 2012 involving all the Toneelhuis actors. In 2013 Guy Cassiers worked with Katelijne Damen on an adaptation of Virginia Woolf’s Orlando which was selected for the Dutch Theatre Festival 2013.
In the 2013-2014 season Guy Cassiers turned his attention to the large theatre repertoire and staged Shakespeare – twice: the music theatre production MCBTH and Hamlet vs Hamlet, based on a text by Tom Lanoye. Hamlet vs Hamlet was well received by press and public alike and was selected for both the Flemish and Dutch Theatre Festivals 2014. Together with Ivo Van Hove, Guy Cassiers was awarded an honorary degree by the University of Antwerp for services rendered to society. In 2014-2015 Guy Cassiers and the ensemble of theatre-makers and actors staged Maurice Maeterlinck’s Les aveugles (De blinden). At HETPALEIS he made a show based on Toon Tellegen’s Het vertrek van de mier (The Departure of the Ant) in cooperation with the socio-artistic organization KunstZ. Cassiers ended the season with Passions humaines,a production based on the work of the 19th century sculptor Jef Lambeaux, with a script by Erwin Mortier and a mixed cast of French and Dutch speakers.
During the 2015–2016 season, he again directed two plays about power and its abuse: Caligula by Camus and De welwillenden (The Kindly Ones), based on the similarly named novel by Jonathan Littell. He also took his interest in opera further with a staging of Francesco Cavalli’s opera Xerse in Lille (FR).
In the 2016-2017 season, Cassiers is making De moed om te doden (Courage to Kill) by the Swedish playwright Lars Norén. In Grensgeval (Borderline) he is tackling work by Nobel Prize winner Elfriede Jelinek. For the Ouverture of the city of Mechelenºs festival Op.Recht.Mechelen, a special concertante reading of Bloed & rozen (Blood & Roses) is being presented. In Japan, he is re-creating the music theatre production House of the Sleeping Beauties, which he originally made in 2009 with composer Kris Defoort, based on the similarly named novel by Kawabata. Later on, in Paris, he will be staging the opera Trompe-la-mort, after Balzac, set to music by Luca Francesconi.
