Keira
Knightly,
apparently
practised
the
facial
expressions
that
she
would
have
during
the
filming
of
solo
sex
acts
in
front
of
the
mirror.
26-year-old
Keira
Knightly
plays
a
young
psychiatric
patient
named
Sabina
Spielrein
in
A
Dangerous
Method.
In
the
film,
the
protagonist
gets
sexual
thrill
from
being
spanked.
Keira
is
quoted
by
the
Sun
newspaper
as
saying
that
once
she
was
done
with
practising
the
various
expressions
she
could
have
for
the
film,
she
would
get
on
to
Skype
with
David
and
show
him
all
that
she
could
do.
He
would
then
help
her
decide
which
expression
suited
best.
A
Dangerous
Method
is
based
on
the
true
life
story
of
Sabina,
who
formed
a
sado-masochistic
relationship
with
her
famous
psychiatrist
Carl
Jung.
