NCIS has been around since 2003, and it has spawned multiple spin-offs. One of the original actors was Pauley Perrette, and she stuck around for most of the series. She had plenty of good and bad experiences while filming the set of the show. 

Perrette has discussed her hair and makeup routine for her iconic role. For example, she had to change her hair color to black constantly. However, the dye that she used ended up giving her a terrible reaction.
