Hailing from Baton Rouge, Louis Herthum has built an impressive and enduring presence in Hollywood, making his mark as both a talented actor and an acclaimed, award-winning producer. Now, while Louis Herthum had small appearances here and there in low-budget films and television series throughout the 1980s, it wasn’t until 1991 that things really started to take off for him. That’s when he landed the recurring role of Deputy Andy Broom on the beloved CBS mystery drama “Murder, She Wrote” (1984–1996). For the final five seasons of the show, Louis Herthum became a familiar face in living rooms across America, bringing depth and authenticity to his character.
After wrapping up his time on the series, Louis Herthum shifted gears in a big way—founding his own production company, Ransack Films, in 1996. From there, he began carving out a strong reputation behind the camera. Over the years, Louis Herthum has produced more than half a dozen films, with one standout being the critically praised 2008 documentary “The Season Before Spring,” which earned him well-deserved accolades.
But even as his producing career flourished, Louis Herthum never strayed too far from acting. He continued to book steady roles, including a memorable run on HBO’s hit supernatural series “True Blood” (2008–2014), where his performance added another layer to his diverse body of work. He also appeared in the A&E crime drama “Longmire” (2012– ), further proving his versatility and staying power in the industry. Through it all, Louis Herthum has remained a dedicated and dynamic force in entertainment—both in front of and behind the lens.
Louis Herthum has appeared in a variety of films throughout his career, with some receiving more acclaim than others. Among his filmography, The Night Stalker (2016) stands out as his highest-rated movie, garnering positive feedback from both critics and audiences. On the other hand, Be Afraid (2017) is regarded as his lowest-rated film, not quite resonating as strongly with viewers. While Louis Herthum has delivered memorable performances in several projects, these two films represent the more polarized ends of his acting range.
