NCIS Los Angeles star Daniela Ruah has revealed that she feared getting fired when she first started acting over 20 years ago. Before joining the hit CBS show, Ruah had primarily worked in Portuguese television, including soap operas like Jardins Proibidos and Filha do Mar. She emphasized the importance of standing her ground and setting boundaries, while also being a team player on set. NCIS Los Angeles recently ended after 14 seasons, but Ruah continues to stay busy with other projects.
