The 10 Sexiest Sci-Fi Actresses In TV History

5. Lena Headey - Terminator: The Sarah Connor Chronicles

The Terminator franchise is one that revolves around A-lister Arnold Schwarzenegger. From the time he appeared on the big screen as the terrifying T-800, fans wanted more and more of him. They also wanted more of Sarah Connor, and while there were a couple of iterations of her on the big screen, there was also another on the small screen.

Linda Hamilton portrayed her in four films, Emilia Clarke in one, and on the TV screen, it was Lena Headey who took over as Sarah Connor.

Not only did Headey handle herself well in the physical role of Connor, but she did it with some sex appeal. True, she doesn’t resemble Hamilton much physically, but she definitely is one of the sexiest sci-fi actresses on the small screen. Unfortunately, Terminator: The Sarah Connor Chronicles only lasted two seasons.
