Around 1947, Hollywood agent Paul Kohner and German filmmaker Ernst Matray also planned a "Caligari" sequel; Matray and his wife Maria Solveg wrote a screenplay called "The Return of Caligari". That script would have reimagined Caligari as a former Nazi officer and war criminal, but the film was never produced. In 1960, independent Hollywood producer Robert Lippert acquired the rights to "Caligari" from Matray and Universum Film AG for $50,000, and produced a film called "The Cabinet of Caligari", which was released in 1962. Screenwriter Robert Bloch did not intend to write a "Caligari" remake, and in fact the title was forced upon his untitled screenplay by director Roger Kay. The film had few similarities to the original "Caligari" except for its title and a plot twist at the end, in which it is revealed the story was simply the delusion of the protagonist, who believed she was being held captive by a character named Caligari. Instead, he was her psychiatrist, and he cures her at the end of the film.
