Can we draw the following hypothesis from the context? 

Context:

Institute Benjamenta, or This Dream People Call Human Life, released in 1996, was the first feature-length film by the Brothers Quay, produced by Keith Griffiths and Janine Marmot. It is based on "Jakob von Gunten", a novel written by Robert Walser. It stars Mark Rylance, Alice Krige, and Gottfried John.
