Kristanna Sommer Løken (born October 8, 1979) is an American actress and model.

Loken was born in Ghent, New York to Merlin “Chris” Loken (a writer) and Rande Porath (a model); both her paternal and maternal grandparents were born in Norway and immigrated to Wisconsin’s Norwegian American community. She grew up on her parents’ fruit farm in Upstate New York. She is also one of the tallest known actresses in the film industry today, standing at just under six feet tall. (as stated in an interview from the Terminator 3 DVD’s special features)

Loken started her acting career in 1996 on an episode of Star Trek: Voyager, and she appeared in several television shows and films, including regular appearances on the television shows Philly, Unhappily Ever After, Mortal Kombat: Conquest, and Boy Meets World. She is probably best known for her performance as the android T-X (Terminatrix) in the 2003 movie Terminator 3: Rise of the Machines. In 2004, she appeared in a German television movie, Die Nibelungen (also known as “Sword of Xanten”), which aired as a 2-part mini-series and set a ratings record. Subsequently, she starred as the leading character in the 2006 film version of the video game BloodRayne, and appeared in director Uwe Boll’s film version of the video game Dungeon Siege, called In the Name of the King.

Loken has hinted that she might be bisexual with a preference for women, as she has stated in an interview with Curve magazine “I have dated and have had sex with men and women and have to say that the relationships I have had with certain women have been much more fulfilling, sexually and emotionally, than of those with certain men…. I connect with an aura, with energy. And if the person with whom I connect happens to be a female, that’s just the way it is. That’s what makes my wheels turn”. She is 5’11 1/2 which is unusually tall for most females, it was quite noted in BloodRayne during her fight scene with Michelle Rodriguez (who is 5’6) about the huge height advantage she has over Rodriguez.
