Fans who adored seeing Wickersham's character, Agent Bishop, on "NCIS" may be surprised to hear that she was fairly anxious about joining the cast (via Showbiz Cheat Sheet). In an interview conducted during MCM Comic Con in London, Wickersham was asked what it was like to join a cast that had already been working together for 9 years. She shared, "It was life imitating art, or art imitating life. It was really scary coming into a show ... a whole cast of people who have worked together for so long" (via YouTube).

Wickersham shared that her nerves eased up once she got to know the cast better. "This cast is the sweetest, most welcoming bunch of people. They were so, so sweet. My nerves, I mean I'm always kind of nervous, but my nerves definitely diffused after hanging out with them for a bit" (via YouTube).

In an interview with Watch! Magazine (via the New York Post), Wickersham expanded on what scared her the most. "People were very attached to Ziva!" Wickersham said. "I wasn't replacing her, but it was scary to come into that. People are crazy about the show. [We] have such wonderful fans."
