What is more important, story or character?

I think in "The Promise" the story is as important as the character. Jens Soering would never be where he is if he was a different person. He always was a highly intelligent person but also a little bit arrogant, he thought that he could handle this situation all by himself in 1985, but he couldn't. And now his strong character in my point of view is the reason why he still is alive after more than 30 years in prison. But as important is the meta-level in this film, the US justice system. It seems to be a system that doesn´t question itself anymore. This is in my point of view as important as Jens Soering's personality.



What made you first want to explore the subject?

I visited Jens Soering the first time 2006 for the Sueddeutsche Zeitung. I am feature editor in this paper. The reactions of the readers were surprisingly powerful. It was the first time I experienced the strength of this story, a love that ends in a double murder. Since then I am writing about this case and trying to understand how Jens Soering survived all these years in prison, and where he gets the power from. What struck me from the beginning was the fact that the trial was so unfair. Why were so many questions never asked, why so many witnesses never questioned, why so many facts ignored? I wanted to get answers.



How long did it take to get the film off the ground?

I was working on this story for more than seven years when I asked Marcus Vetter if he would like to do this movie together with me. I already had many contacts so it was an easy start. I organized the interview with Jens Soering in prison and after that, many doors opened.



What were you most surprised to learn in the course of production?

I was surprised that some people never were interested in the facts in this case. Now it is scientifically proven that there was the blood of two other men at the crime scene. How does this fit the verdict? It was always said that Jens Soering did this crime all by himself. Why are so many people not interested in this? Maybe the real murderers are still free somewhere in the US or the world. And nobody is interested?



What have been the differences in reception to the film in countries it has now travelled to?

For me by far the most interesting screenings were the ones in the US. I wasn't sure how the US audience would react. Angry, because a German film team is questioning the US justice system? It was the opposite. When I was in Charlottesville, Virginia with the movie the reaction was totally surprising. It was by far the most committed audience. You could feel their anger...

Which documentary has most inspired you?

"Workingman’s Death" by Michael Glawogger and "In the Basement" by Ulrich Seidl.

My favorite at this year's IDFA: "Weiner" by Josh Kriegman and Elyse Steinberg.

You have to search for the beauty in the horrible, said Ulrich Seidl in an interview.

I think that is a interesting approach.

Elizabeth Haysom, she first accepted to be interviewed, than she cancelled our meeting unfortunately. I would have loved to show her side of the story as well.
