This is the last film starring Mari Somei, as the 25-years-old actress mysteriously disappeared in 1988. Her fate remains unknown.
Artworks visible in Painter's house were created by Kazuki Tomokawa, Japanese musician and painter.
The Painter fits the archetype of crazy and murderous artist found in many works of Hideshi Hino, sometimes with a flavor of self-caricature.
This Japanese movie from 1988 is the fifth and penultimate one in the Guinea Pig series, but it's the first of two in the second wave of the series - the first one in the series to have been produced and distributed (beginning on July 25, 1988) by Japan Home Video, which revived the series a year and a half after Sai Enterprise, the company which previously produced it, went bankrupt. That's why the movie's onscreen Japanese title doesn't include a volume number.
