Blue Bloods, a long-standing cop show, has interesting behind-the-scenes facts. Tony and Andrew Terraciano, who play Danny Reagan’s sons, are real-life brothers. Tom Selleck’s iconic mustache almost got shaved off in the first season, but CBS Executives insisted on keeping it. The Reagan family dinner scenes took up to five hours to film, and the iconic house exterior is in Bay Bridge, Brooklyn. Adrian Matia, an EMT in real life, played an EMT on the show. Amy Carlson’s departure from the show shocked fans, and Jennifer Esposito left due to health reasons, resulting in her being fired. Blue Bloods faced challenges early on, including a potential move to Toronto and conflicts with its creators over the show’s direction. Lastly, the show received criticism from the Catholic League for an episode portraying the Catholic Church as “behind the times.” These insights offer a glimpse into the show’s behind-the-scenes dynamics.
