Summer made this video interview during her appearance at FedCon 2009. She talks about her audition for the role of Cameron in Terminator: The Sarah Connor Chronicles, being a huge fan of Josh Friedman's writing and her excitement to play the role when the producers explained to her how Cameron would be portrayed in TSCC.
Once they [the producers] explained to me what they were trying to do, wher her [Cameron] being the most advanced model, the most capable of imitating humans, I got really excited. Because [...] it's fun to try to be creative playing a robot, but it's even more fun to play a robot who is really good at being human.
Unfortunately, Summer's audition tape isn't included in the DVD's special features. However, here's a little bit of context about her audition (mostly from Wikipedia):
Four years prior to The Sarah Connor Chronicles, Josh Friedman developed another pilot in which he wanted to cast Summer Glau. However, she was already committed to Serenity and The 4400. Despite this, Friedman "always kept her in mind" and, as the pilot for The Sarah Connor Chronicles was being cast, she was called in to audition. Summer did not plan on auditioning, however, because she had a preconceived idea that the producers wanted "statuesque, icy blondes" for the role, and felt that she did not suit such an image. She agreed to audition after being encouraged by her mother to do so and became comfortable with the idea of performing upon the realization that Friedman had a different idea for how Terminators would be portrayed on the show.
The scene used for Summer's audition involved a crying Cameron discussing with John the future in which she meets him, how he saves her life and "how [she] feels about [him]", even though as a robot she is technically incapable of any feeling at all. The audition continued with Friedman and the other producers watching Glau's fight scenes from her previous work on Firefly and Serenity. Summer was cast in February 2007 with Friedman feeling that "there was really no second choice [and that Cameron was] basically written for her.
