Julian Schnabel’s ravishingly tactile and luminous new film takes a fresh look at the last days of Vincent van Gogh, and in the process revivifies our sense of the artist as a living, feeling human being. Schnabel; his co-writers Jean-Claude Carrière and Louise Kugelberg, also the film’s editor; and cinematographer Benoît Delhomme strip everything down to essentials, fusing the sensual, the emotional, and the spiritual. And the pulsing heart of At Eternity’s Gate is Willem Dafoe’s shattering performance: his Vincent is at once lucid, mad, brilliant, helpless, defeated, and, finally, triumphant.
