Gachot met Dr. Beat Richner also known as Beatocello in Phnom Penh in 1996. The filmmaker was commissioned by a Swiss music label to record a CD in a pagoda with Richner’s playing Bach suites on his Cello. The CD should promote and help to collect money for Richner’s children’s hospitals Kantha Bopha in Cambodia. Richner and his project fascinated the filmmaker and a relationship developed that hold over twenty years until the death of Richner in September 2018. Gachot and Richner spoke on the phone almost every day. Richner called Gachot Steven, like Steven Spielberg, making fun of him, and Gachot called him Pablo, like Pablo Casals, the famous Spanish cellist. During this time, Gachot could realised five films about his unique humanitarian achievement in the country of the Khmer. Today the five Kantha Bopha hospitals of Dr. Beat Rcihner treat 80% of the sick children, free of charge.
