Ekiben (1999)

Kaji is a director of over 1000 porn videos. While dreaming of becoming a feature film director someday, he sinks deeper into the tepid morass that is the Japanese porn industry. One day, he auditions an porn movie starlet named Saki who confesses to dreams of the big screen. Kaji senses a kindred spirit in his newfound star, but as a result becomes exceedingly demanding of her performance. Saki endures repeated humiliations by Kaji, who uses her as an outlet to vent his own frustration. Bit by bit, however, they begin to gel. Saki lands a role in a movie. Kaji regains a semblance of joy in his work and discovers new inspiration.
