Strahovski sent in her audition tape for the TV series Chuck while in the United States auditioning for roles in other shows, namely NBC's 2007 series Bionic Woman. She was contacted by the producers of Chuck the next day to come in and run lines with Zachary Levi. The producers called her back a week later letting her know she had been cast as Sarah Walker. Six months later, she moved to the United States. Strahovski adopted the more phonetic spelling of Strahovski as her stage name in place of Strzechowski at this time, at producer Josh Schwartz's behest for the sake of easier pronunciation.
