"

While attending a film festival, Franz met Austrian actor Peter Kern, a controversial[citation needed] actor and filmmaker.[1] Recalling their meeting, Franz said: "[I talked to him] for several days actually. I only talked to him because I felt so sorry for him, but I got to know him. I really thought that he was a very fascinating character and someone should do a movie about him. He used to work with Rainer Werner Fassbinder in the German cinema of the ‘70s. He was kind of erschwerte in that group. I mean, he was crazy. I thought he was really crazy."[1] Franz decided to follow Kern for the next two years, directing and writing a documentary film on him with Fiala.[1] The documentary, titled Kern, was released in 2012.
