These Behind-the-Scenes Mistakes Made Their Films Better

Slap Happy Gibbs

NCIS Special Agent Gibbs is known for his stern and no-nonsense demeanor, and he doesn’t hesitate to deliver a swift smack to the head when dealing with his occasionally obnoxious colleague, Agent Anthony DiNozzo. These head smacks became a recurring and humorous element of the series.

What many fans may not know is that these memorable head smacks were not the brainchild of the show’s writers. Instead, they emerged from frustration when Mark Harmon, the actor portraying Gibbs, playfully slapped his co-star Michael Weatherly during filming. The spontaneity of the gesture fit the characters perfectly, and it evolved into a running gag throughout the series, adding a touch of humor to the often serious investigations.
