Early life and training

She started as a classical ballerina, which provided her with a good base for developing as an actress because dance requires perfect control, timing and ability to perform physical actions well. Her way of becoming a popular Hollywood actress is very different from other actors' ways, as she became famous in genre shows requiring her to do something unusual like still poses, movements and creating atmosphere. Even in case of playing quiet and closed characters she manages to impress the public by giving them something special and individual.

Breakthrough in genre TV

Glau's initial work in television was associated with Joss Whedon's creations. After he saw Glau's appearance in "Angel", Whedon invited her to play River Tam. The character was a brilliant and damaged young woman whose actions changed in moments from fragility to explosive nature. She later had success playing this character in the film "Serenity". Later she added to her acting repertoire playing the character of Tess Doerner in a show called "The 4400" from 2005 till 2007.

Later screen work

In her later films Summer Glau successfully demonstrated what she can do. One of the biggest successes she achieved was when she played Cameron, the Terminator sent to help John Connor.
