In October 2014, it was announced that Gore Verbinski would direct the film, with a script by Justin Haythe, for New Regency Pictures. By early June 2015, Dane DeHaan, Mia Goth and Jason Isaacs were cast for the film. Principal photography for the film began in late June, lasting 5 months. Interior shooting took place at Beelitz-Heilstätten, a huge abandoned hospital complex and mainly at Babelsberg Studio in Potsdam. The building itself and the area around it have been completely renovated after being a ruin for decades. 750 windows (1,000 sq m of glass), 350 doors, 1,200 sq m of walls and many other things had to be replaced or repaired to restore the original look of the building. Exterior shooting took place at Castle Hohenzollern in the German municipality of Bisingen. The castle was closed to the public for filming from July 13 to July 24, 2015. Aside from Hohenzollern, parts of the film were also shot in Saxony-Anhalt and Zella-Mehlis, Germany. The scenes in the grotto were planned to be shot in Vienna but the shooting was canceled shortly before the start. The film studio in Babelsberg therefore had to build an entire grotto of 2000 sq m on their own. The film received funds of €8.1 million, from the German Federal Film Fund (DFFF), as well as €500,000 from Medienboard Berlin-Brandenburg.
The film stars Dane DeHaan, Jason Isaacs and Mia Goth. DeHaan gave a fine performance despite portraying a completely unlikable character. Isaacs and Goth both gave eerie and unsettling performance as two characters who are not what they seem beneath the surface.
