Released in 2014, The Circle depicts the story of Ernst Ostertag, Röbi Rapp and other members of Der Kreis, a gay organisation and publication that fell under investigation by the Swiss police after several gay men were killed. Written by Christian Felix, Ivan Madeo, Urs Frey and director Stefan Haupt, the docudrama was shot entirely in Zurich, Switzerland. The film stars Matthias Hungerbühler and Sven Schelker as Ostertag and Rapp respectively.
Though Zurich was the escape for many gays, much of their activity had to remain underground as the gay community was still subject to raids, threats and being personally outed in newspaper articles. As a teacher on the verge of being confirmed for tenure, either occurrence could prove to be very career-limiting for Ernst – if not career-ending. Even the otherwise flamboyant, cross-dressing Robi kept up a far more straight-laced appearance on his day job as a barber.
