Glau received a scholarship to a ballet company and was homeschooled from grades 3 to 12 to accommodate her ballet training.

Glau's first television credit was a guest role as a ballerina on a 2002 episode of the television series Angel.

There she caught the eye of director Joss Whedon who later cast her in his critically acclaimed but short-lived TV series Firefly as River Tam, a role she reprised for the show's feature film sequel Serenity.

Glau previously auditioned for the role of a Power Ranger (White Wild Force Ranger Alyssa Enrilé) in Power Rangers Wild Force but lost to actress Jessica Rey before meeting Whedon.
