Vital

Vital (ヴィタール ) is a Japanese film made in 2004. It was directed by Shinya Tsukamoto and stars Tadanobu Asano as Hiroshi Takagi, a man whose girlfriend dies and who loses his memory in a car accident.

The original concept that inspired Vital was the image of medical students making sketches during a dissection. Tsukamoto visited a medical school and observed a dissection while writing the screenplay, which was originally titled: Dissection Film Project. Leonardo da Vinci's anatomical sketches were a direct inspiration.[1]
