Creative differences are a common occurrence in the entertainment industry, and they can sometimes lead to an actor leaving a show. In the case of Mark Harmon and NCIS, it is reported that Harmon had disagreements with the show's producers over the direction of his character, Leroy Jethro Gibbs, and the overall creative vision for the show. This is a significant factor in understanding why Harmon left NCIS, as creative differences can be a major source of frustration and dissatisfaction for an actor.

When an actor has a different vision for their character than the show's producers, it can create a conflict that is difficult to resolve. The actor may feel that their character is not being developed in a way that is consistent with their own interpretation, or they may disagree with the overall direction of the show. This can lead to tension between the actor and the producers, and it can ultimately lead to the actor leaving the show.

In the case of Harmon and NCIS, it is not clear exactly what the creative differences were that led to his departure.
