There was a time when we all knew Michelle Trachtenberg as Dawn, Buffy's little sister who wasn't really her sister but was actually her sister. (Confused? Watch Buffy the Vampire Slayer. How have you missed out for so long?) She's also known for her part as Georgina Sparks on Gossip Girl. But now Trachtenberg is taking on a much different kind of role as Russian immigrant Marina Oswald on National Geographic's Killing Kennedy. She plays the wife of Lee Harvey Oswald (played by Will Rothhaar, pictured below), John F. Kennedy's assassin. Killing Kennedy chronicles the final years of John F. Kennedy and Oswald and is based on the book by Bill O’Reilly and Martin Dugard. It will debut in November.
