At the Maxim Gorki Theater in Berlin, Kammerer appeared in Youth Without God directed by Nurkan Erpulat in 2019, and at the Salzburg Festivals he made his debut in 2019 in Summer Guests by Maxim Gorki in the role of the student Simin.^[4][3] Martin Kušej brought Kammerer to Vienna's Burgtheater as a permanent ensemble member at the beginning of the 2019/20 season, where he debuted as Duke of Medina-Sidonia in Schiller's Don Karlos. In October 2019, Kammerer appeared at the Vienna Academy Theater in a production by Ene-Liis Semper and Tiit Ojasoo as Behemoth in Master and Margarita by Mikhail Bulgakov, and in The Little Witch by Otfried Preußler, which premiered in November 2019 at the Vestibule of the Burgtheater.^[5][6]

All Quiet on the Western Front

In 2022, Kammerer made his big-screen debut appearing as Paul Bäumer, the lead role in Edward Berger’s German-language adaptation of the Erich Maria Remarque 1928 novel All Quiet on the Western Front. Berger was casting for the role of Bäumer when Kammerer was identified by Sabrina Zwach, wife of the film’s producer, Malte Grunert. Grunert was so impressed by Kammerer’s performance at the Burgtheater he offered him an immediate audition and gave a personal recommendation to Berger.^[10][11] Berger described seeing Kammerer’s face the first time and being struck by the fact he "was already so old-fashioned and so classic looking, so pure and so innocent". They continued to cast for four to five months and Berger said:

I saw some 500 young actors. And we invited Felix back again and again. And every time, he just got better and better, just growing into the role. At one point, it was clear, it had to be him. It was a real discovery.^[12]

Kammerer's performance in All Quiet on the Western Front has been widely praised. Maggie Lovitt for Collider wrote "In his first performance on-screen, Kammerer proves himself as a promising newcomer on the global stage. Paul Bäumer is not an easy role to take on; the physicality of the role alone might crush a performer, and that's without considering the great emotional toll undertaken to portray the shame, depravity, and agony of war. Paul is the heart of the film, and Kammerer effortlessly bares his soul to the audience as the war takes and takes and takes from his character."^[13] John Nugent of Empire (magazine) described his performance as "hugely impactful even when caked in mud".^[14] Danny Leigh in The Financial Times describes him as a "remarkable newcomer",^[15] with Kate Connolly in The Guardian describing how "Bäumer is tenderly and brilliantly played by newcomer Felix Kammerer".^[16] Justin Chang for IGN says "Kammerer may be a newcomer, but his performance is nuanced and chilling in equal measures. Bäumer isn't just out of his depth – each and every moment of life on the front lines leaves him desperately trying to catch his breath. Kammerer captures every moment with an agonizing depth that he wears on his sleeve throughout. This truly incredible performance highlights the horror of a young soldier forced to confront every nightmare imaginable. Bäumer is under the lens, as every moment pushes him further away from the young man he was."^[17]
