A breathtakingly beautiful film. The Fisher King is one of the most perfectly executed movies of all time, from the stunning and highly imaginative screenplay to the haunting quality of the direction and the sheer genius of Williams and Bridges, who both turned in the performance of a lifetime. Add to that a supporting cast made in heaven and you basically can't go wrong.
While the film succeeds brilliantly even as a basic story of star-crossed individuals working out their joint karma, it is the concept of the soul's journey homeward that drives the deeper levels of The Fisher King.
As Barbara G. Walker and others have pointed out, the Grail is actually a representation of the Womb of the Great Mother, from which we all came, and to which we shall all return. Like Finnegan and Bloom/Ulysses, The Fisher King's two heroes find salvation in the simplicity of surrender and in the almost Faustian embracing of the Sacred Feminine, as embodied by the two female leads. Carrie Moss's Trinity (The Triple Goddess) also provides this transcendent nurturing to Keanu Reeves's character in The Matrix.
If you were to buy The Fisher King, The Matrix, Groundhog Day and Jacob's Ladder, you would have in your possession some of the most profound philosophical insights in the history of the human race.
A true masterpiece. Dang, it even features a cameo by Tom Waits.
