In 1994, when eight years old, she won the role of Isabel in the film
Nessie - Das Geheimnis von Loch Ness (1996), having beat off thousands of other hopefuls who also
auditioned. The film's
John Henderson said that the role required a child who
'possessed that intangible quality that would make [the audience] buy
the fact that she holds the secret of the Loch', which was why Kirsty,
with her 'Bette Davis eyes', was so perfectly cast.
