At the end of every act, the audience hears a dramatic noise. You know the one. As soon as the noise is heard, the scene freezes and goes to black and white. Well it turns out that the dramatic noise was created by Donald P. Bellisario with a mere microphone.
Cameos
Two very real-life NCIS agents have made cameos on the show! That’s right, Special Agent David Brant appears in the season three episode titled “Frame Up”. Whereas the former director Thomas Betro appeared in “Identity Crisis” just two seasons later. Both agents used their real names as their character name on the show.
