Summer Glau was considered the Farrah Fawcett of the sci-fi world; a poster girl for die-hard fans of graphic novels, superheroes, and cyborgs. Playing erratic and troubled child prodigy River Tam in both the cult televison series "Firefly" (2002-03), about a renegade spaceship crew, as well as its big screen sequel, "Serenity" (2005) became the actress' breakout role. In 2008, Glau took sci-fi leading lady to the next level, as female Terminator Cameron Phillips/Allison Young on the FOX series, "Terminator: The Sarah Connor Chronicles" (2008-09). Arnold Schwarzenegger and Christian Bale may have been the stars of the blockbuster film series, but on the small screen, Glau kicked and punched her way to proving she was one of the more viable female action stars of the medium.
