Katharine broke into acting act an early age winning parts on films such as Cousins, Cold Front and shows like MacGyver. As time went on Katharine won bigger roles which would eventually build up to a lead role in Ginger Snaps acting alongside her friend and co-star Emily Perkins. It would seem that Katharine has been stalking Emily, being born in the same hospital, attending the same schools albeit 5 years behind Emily.
Katharine: I have some friends that made movies like that when they were eight, nine years old, and they got stressed out, their hair and eyelashes fell out and they had to go into therapy. Kids kind of know 'the movie' isn't real, but at the same time.
