Agent Alexandra “Alex” Quinn quickly became a fan-favorite on the beloved hit crime series NCIS — so, why would Jennifer Esposito, the actress who effortlessly played the role for 24 episodes, decide to leave NCIS after only one season? Turns out, there was no drama with the network or her co-stars, she was just looking for different career opportunities. Nothing wrong with that! "It was a great experience," Jennifer once said in a statement to Deadline about her departure. "I could not have asked for a better opportunity than to work with the NCIS cast and producers." Shortly after leaving NCIS, the 45-year-old actress went on to land a co-starring role in the feature Speed Kills alongside John Travolta.
