In 2008 Marie Steinmann and Tom Tykwer founded One Fine Day, a non-profit organization which initiates and supports art education projects for children and adolescents in East Africa, especially in Kenya.
The production company One Fine day Films was one of those projects; eventually Tom Tykwer helped to supervise the low-budget film production SOUL BOY, a joint Kenyan-German film project which was shot almost exclusively in East Africa's largest slum, in Kibera (Nairobi).
