Alice 2 creator American McGee has revealed his inspiration for the story behind the dark sequel on the fairytale based series.
We're not just talking a book and a film here, McGee actually posted "research links" to Wikipedia pages on the concept of 'Active imagination', Viennese psychoanalyst Herbert Silberer and a thesis called 'C. G. Jung and the Alchemical Renewal' about dreams and Gnosticism.
That's some heavy stuff right there.
Alice 2 was announced back in 2009 and continued the warped interpretation of the Lewis Carroll, not that it wasn't warped to begin with.
