Brian Dietzen has shocked longtime NCIS fans with a revelation that few saw coming. In a recent interview, he opened up about the early days of filming with Pauley Perrette, and admitted that not everything behind the scenes was as smooth as it looked on-screen. While their characters, Jimmy Palmer and Abby Sciuto, had a fun and quirky connection, Dietzen confessed that filming those scenes wasn’t always easy.

According to Dietzen, Perrette’s high-energy style clashed with his more laid-back approach in the beginning. “It was chaotic at times,” he said. “Her vibe was very different from mine, and it took some adjusting.” He went on to describe certain filming days as “stressful,” hinting that not every take ended with smiles.

Despite the rocky start, Dietzen clarified that over time, mutual respect and understanding developed between them. He praised Perrette’s dedication and admitted that their early challenges ultimately made their chemistry stronger. “What made it hard also made it real,” he added.

The unexpected honesty from Dietzen has sparked a wave of reactions from fans, many of whom never guessed there was tension between the two. But in the world of NCIS, it seems even the toughest moments can lead to the most memorable performances.
