You know her from "Gossip Girl," "Buffy the Vampire Slayer," and "Harriet the Spy," but chances are that you still won't recognize Michelle Trachtenberg in the photo above, as she portrays Marina Oswald in National Geographic Channel's upcoming movie "Killing Kennedy."

Trachtenberg is shown holding the young actress who plays one of Marina's two daughters, June and Audrey, her children with Lee Harvey Oswald (Will Rothhaar), the man who was assassinated himself before he could be tried for the assassination of John F. Kennedy.

Rothhaar played Jason Alexander's son in the short-lived 2004-05 CBS comedy "Listen Up!" and has made guest appearances on "CSI" and its two spinoff series, "CSI: Miami" and "CSI: NY."
