John Krasinski and Jenna Fischer were cast in their respective roles as Jim and Pam, the main love interests. Krasinski had attended school with B. J. Novak, and the two were best friends in school. Fischer prepared for her audition by looking as boring as possible, creating the original Pam hairstyle. In an interview on NPR's "Fresh Air", Fischer recalled the last stages of the audition process for Pam and Jim, with the producers partnering the different potential Pams and Jims (four of each) together to gauge their chemistry. When Fischer finished her scene with Krasinski, he told her that she was his favorite Pam, to which she reciprocated that he was her favorite Jim. Adam Scott and John Cho both auditioned for the role of Jim, and Kathryn Hahn also auditioned for the role of Pam.
