"When I received the letter, I only knew what he looked like and a few facts from Wikipedia. Since he looked old – he was around 50 and I was 21 – I didn’t find him attractive at all. That was all I knew at that time, so when I decided to make a film about it, I researched a lot. I watched a lot of documentaries and read a lot about him. I also tried to contact his niece and his other girlfriends, but I really got to know him through the many original letters Eva brought from California to Germany when I interviewed her, and I figured out that he’s not that easy. The way the media described him and how he acted was as if he was a dangerous Satanist because of the publicity. But he was more a wannabe rock star, evil I guess, but I figured out that he’s wasn’t as smart as he looked, he was not well educated, which was also a turn off for me. Actually, he was a poor, lonely guy with almost normal feelings. He cried, even, for example, when Eva left or when he missed her, and he loved her a lot, I felt, but when it came to his crimes he didn’t have any regrets or compassion. So, I tried to show those sides of him in my film, too."
