The Swedish title, "Frände av Ljus," may be translated "Kin of Light." The text on the home page reads: "The film revolves around the dramatic life of Ivan Aguéli, his versatility, genius and experimental painting. We want to show Aguéli as the multifaceted man he was, with strengths and weaknesses. A seeker, both after real life and higher things. The continuation of the project now depends on funding. In that process we are also seekers..."
My thanks to Anthony Fiscella for drawing the film to my attention.
