It s worth noting that Angel of Darkness, while technically a sequel to the first season, works as its own standalone story. Brühl s Dr. Kreizler reunites with his rag-tag investigative cohorts Sara Howard (Dakota Fanning), now running her own detective agency, and New York Times journalist John Moore (Luke Evans) as they work to solve a string of baby murders amid a backdrop of political and cultural turmoil. The themes of women s rights, police brutality, and racism create a conflicted, yet timely, story here.Ahead of the show s return, Rotten Tomatoes spoke with Brühl about how his character has evolved since the series premiere, whether the show s disturbing subject matter gives him nightmares, how the themes explored in The Alienist: Angel of Darkness are relevant today, and if the COVID-19 shutdown delayed his work on The Falcon and The Winter Soldier.(Photo by TNT)Aaron Pruner for Rotten Tomatoes: This season focuses a lot on Sara Howard, while Kreizler is cultivating his own relationships. Has Kreizler, as a character, changed in how you interpret him since you first took on the role?Daniel Brühl: Knowing about Sara s psychological skills, Laszlo Kreizler is eventually willing to share power and to give in and to let Sarah Howard be in charge of that new mystery and of that new case. He becomes, emotionally, a more open-minded man thanks to the friendship with Sara and John and eventually even finds a kindred spirit, someone who he finds very fascinating.It s so interesting because my wife is an alienist in real life. And she told me that many times the most brilliant psychologists you know, become very nervous when they have to deal with, you know, their own introspection and their own inner life. So they may be brilliant in, you know, analyzing their environment, and yet, they have problems in expressing what they are going through.The theme of child murder continues in season 2. Is it tough to separate yourself from the dark subject matter of the show?Brühl: It didn t affect me that much when we were shooting the actual show, but watching it now gives me nightmares. I m the father of a little boy and expecting my second baby to arrive soon. The fact that this show this time around deals more with motherhood and fatherhood, respectively, felt more universal. It was also interesting to realize how engaged my wife was when she watched the show. She said that it resonated more with her than the first season.(Photo by Nelly Kiss/TNT)This is a period piece, yet the issues explored in the series continue to feel quite timely — women s rights, sensationalism in the news, police corruption, income inequality, and racism. What message are you hoping viewers will take away from watching?Brühl: It is very sad to see how long it takes for mankind to really make a change. It s funny how history goes in waves. I wouldn t say that it always goes in the wrong direction. Sometimes we advance, sometimes we evolve, and then, sometimes we go three steps back. So it is sadly fascinating to see that a story set in 1897 and a book written about that period that was published in the 1990s still feels so current.And what the story tells us is that it always takes a couple of courageous liberal modern minds to make a change. Unfortunately, mankind needs to have the worst things happen in order to move on. So the eruption that, fortunately, we witness these days internationally, due to the things that happened in the U.S., gives me a bit of optimism, because that avalanche, that eruption, and that message that racism has to stop, is being heard loudly and clearly at the moment. I hope that, finally, we will change and, hopefully, carry on doing so. We always have to hope that we will learn something from history.
