Jean Painlevé was a film director, critic, theorist, and animator, yet his interests and studies also extended to mathematics, medicine, and zoology. Amazingly, all these disparate strands came together in a groundbreaking, decades-spanning artistic career. Operating under the credo Science is fiction, Painlevé forged his own unique cinematic path, creating countless short films for both the viewing public and the scientific community. Moreover, he was also one of the first filmmakers to take his camera underwater. Surreal, otherworldly documents of marine life, these films transformed sea horses, octopi, and mollusks into delicate dancers in their own floating ballets.
