Many of Ressler’s works have been realized in collaborations: “Boom!” focuses on the central contradictions of globalized capitalism (with David Thorne), “European Corrections Corporation” on the phenomenon of prison privatization (with Martin Krenn), and “What Would It Mean To Win?” on the protests against the 33rd G8-summit in Heiligendamm (with Zanny Begg).
Voss usually played at the tennis facilities at Heiligendamm, where he frequently met with Russian Duchess Anastasia Mikhailovna and countess Clara von der Schulenburg.
