Father Actor Z (2014)

Mitsuo Mameda, a 52-year-old man at rock bottom after failing at his snack bar, accumulating debt, and losing his family, unexpectedly enters the world of adult film acting. He takes a job as a "juice actor," the lowest rank in the industry, and befriends veteran actors Hachiya and Omae, sharing a living space with them. Their lives are upended when Yuria, a well-known adult film actress, suddenly appears and requests to live with them. Seiji Nakamitsu, a seasoned actor with over 500 appearances in "pink movies," stars as Mameda.
