Who Plays Katherine Casillas In NCIS: Los Angeles?

Well before she joined the cast of "NCIS: Los Angeles," Moon Bloodgood had already established herself in a handful of other dramatic television series. After appearing briefly in one-episode arcs on "Just Shoot Me," "Fastlane," "CSI," "North Shore," "Monk," and "Rocky Point," the actor landed the recurring role of Rita Shelten in ABC's sci-fi drama "Day Break." Following her season run on the series, Bloodgood starred alongside Kevin McKidd ("Kingdom of Heaven," "Brave") as the time-traveling protagonist Livia Beale in NBC's 2007 sci-fi series "Journeyman." The actor returned to television in 2009, portraying Detective Paxson in three episodes of "Burn Notice," but it was a return to the world of sci-fi and postapocalyptic narratives that most successfully put the actor on the primetime map.

From 2011 to 2015, she starred as former pediatrician Anne Glass in TNT's "Falling Skies." The alien invasion series, co-executive produced by Steven Spielberg, received two Emmy nominations for outstanding special visual effects and earned Bloodgood a Saturn Award nomination for best actress on television (via IMDb). Three years later, Bloodgood officially joined the CBS lineup with her role as EMT Rox Valenzuela in Michael Seitzman's medical drama, "Code Black."

In addition to her long-established career in television, Bloodgood is also known for her roles in a handful of films with distinctly different tones, genres, and critical responses.
