Q:Given the following context:  In his first leading role Ben Mendelsohn plays Danny Clark, a bumbling eighteen-year-old guy. He knows what it takes to be cool and have some style, it is just that he seems to struggle to get there. Danny has enthusiasm and passion and only wants two things more than anything in the world. A Jaguar XJ6 and a date with the gorgeous Joanna Johnson (an early role for then 17-year-old Claudia Karvan). Get these and his life will be complete. Unfortunately for Danny, when he finally gets the courage up to ask Joanna out, he somehow manages to promise her a ride in his new Jaguar. She is not particularly impressed by cars, but still agrees to his invitation. The problem is, Danny does not own a Jaguar. His form of transport is his recently received birthday present - and it most certainly is not a Jaguar. His eccentric parents have decided to pass on their pride and joy to Danny for his use. Their 1963 Nissan Cedric has been in the family for years and is immaculate  but extremely uncool. Danny is aghast at the thought of driving around in a car as dorky as a Cedric and, with the promise of a date with Joanna and the need for a Jaguar in a hurry, decides to trade in the old Nissan. He heads out to search the car yards to find his dream machine.  answer the following question:  What is the full name of the person who is not particularly impressed by cars?
A:
Joanna Johnson
