太秦ライムライト (2014)

Fewer samurai films are being made, and the Uzumasa studio has fallen on hard times. One day, veteran "kirareyaku" (whose job it is to be felled with a sword by a film's star) actor Kamiyama is tasked with teaching sword action techniques to fledgling actress Satsuki. A few years later, the now-retired Kamiyama is visited by Satsuki, who has become a popular star.
