Among the few women around him, Monica was neither temperamentally nor skill-wise fit for the role; Sarah was too young, not to mention a bit too pretty; Liv had already arranged another movie and was currently in the exploratory phase, not to even mention ingesting anything—her temperament was also unsuitable; as for Kate, she hadn't returned to his side yet and her features were too delicate, nothing like the look of an American girl. So, after much deliberation, Julia was the only suitable choice.
First, she wasn't the kind of actress known for her looks; second, her acting was beyond reproach; third, and most importantly, her consistent image was that of a strong, independent woman, which matched the character perfectly. However, when Adrian asked Julia if she was interested, she was preoccupied with the troubling thoughts about him and Monica and declined without even looking. Adrian planned to revisit it after some time, but he got so busy that he completely forgot about it.
