Chicago Fire stars Daniel Kyri and David Eigenberg bring a unique chemistry to the screen as Darren Ritter and Christopher Herrmann. Known as the “odd couple” of Firehouse 51, their dynamic combines Ritter’s calm presence with Herrmann’s unpredictable energy — a connection that also reflects the actors’ off-screen relationship.
Kyri, 29, who joined the show in 2018, admires his co-star Eigenberg, calling him a “wonderful friend” and mentor. “Working with David is a bit like acting alongside a tightly leashed tornado,” Kyri told Us Weekly, laughing. He praised Eigenberg, 60, for his skill and precision, saying that each scene with him is an opportunity to learn. “He’s one of my greatest teachers in this process,” Kyri added, describing his work with Eigenberg as both challenging and rewarding.
The quirks that fans see in Herrmann’s character aren’t just scripted, Kyri revealed. “Those little gems of his spirit come from the creative process itself,” he explained, sharing that Eigenberg’s personality shines through his character, bringing an authenticity that fans love.
Their on-screen partnership, one of Kyri’s favorites, promises to evolve in the upcoming season. In the October 9 episode, Ritter faces a serious injury during a call, which will cast light on the impact he has on his fellow firefighters and the importance of his role in the firehouse. Kyri shared, “This episode will reveal an incredibly human side to everyone at Firehouse 51, highlighting how deeply they care for one another.”
Beyond acting, Kyri is also making strides in his music career. His new single, “Maybe,” drops on October 11. Following the release of his upbeat debut track, “Dreamland Ave,” “Maybe” offers a more personal reflection, exploring the struggles of relationships. Kyri calls it his “crying in the club” song, adding that listeners can dance to it while connecting with its deeper, emotional message.
“It’s my way of reclaiming the narrative and reminding myself it’s okay to make mistakes in love and life,” Kyri said. Through acting and music, Kyri is pursuing a career that balances self-expression and storytelling in meaningful ways.
