You know her as the evil Georgina Sparks from "Gossip Girl" but nowadays Michelle Trachtenberg has traded in her stylish Upper East wardrobe for clothes from the 1960's in order to portray Marina Oswald.

Does that name sound familiar? It should, she was the wife of Lee Harvey Oswald, the man who was charged with assassinating former president John F. Kennedy

Trachtenberg will star in an original TV movie from the National Geographic channel titled, "Killing Kennedy." Although the assassination happened on November 22, 1965 Marina Oswald still believes that her deceased husband is innocent, according to Us Weekly.

Lee Harvey Oswald was killed by a nightclub owner before his case even went to trial. Now 50 years later the story still inspires film projects.

Michelle Trachtenberg exclusively shared her excitement and challenges with the magazine about playing a Russian born woman.

The actress said, "I am so excited for the challenge to portray Marina Oswald, and to do my first role speaking only in Russian."

"I'm the only actor playing someone who is still alive, so I want to stay as true to her as possible. This is a story about JFK's assassin, Lee Harvey Oswald and his wife Marina. And it is fascinating."

Also starring in the film will be "Once Upon a Time" actress Ginnifer Goodwin as Jacqueline Kennedy, "Parks and Recreations" star Rob Lowe as the late president, and Will Rothhaar will play Lee Harvey Oswald.

The film will be based on the best selling book of the same name by Bill O'Reilly and Martin Dugard. The film is set to begin production in June in Richmond, Virginia.
