Nine
years
have
gone
by
since
Ko
happened.
Be
it
the
romance
incorporated
in
the
thrilling
storyline
or
the
songs,
the
movie
is
as
fresh
as
ever.
The
film
released
on
April
22,
2011,
had
opened
with
positive
reviews
from
the
audience.
It
was
nominated
for
six
Filmfare
Awards
South
winning
in
two
categories
and
Tamil
Nadu
State
Film
Awards
winning
in
4
categories.
As
the
movie
completes
its
incredible
9
years,
let
us
take
you
to
the
flashback
which
made
Ko
a
unique
cinema
experience.
Search
For
Mr.
Perfect,
The
Hero!
Going
back
in
time
when
the
movie
was
in
its
inception
mode,
it
is
said
that
the
director
KV
Anand
was
searching
in
a
full
swing
for
the
Mr.
Perfect
to
essay
the
character
of
Ashwin
Kumar,
a
photojournalist.
The
director
had
approached
almost
all
actors
of
Kollywood.
Though
a
top
producer
of
the
industry
had
suggested
to
rope
in
Ajith
for
the
movie,
Anand
stated
that
the
movie
was
not
suitable
for
Ajith's
mass
stardom.
Chiyaan
Vikram
was
zeroed
in
for
the
movie
after
he
was
impressed
with
the
narration.
But
later,
he
walked
out
of
the
project
as
he
had
already
signed
in
for
another
movie
and
had
date
issues
to
cover
up.
Karthi
and
Suriya
were
also
rumoured
to
be
considered
for
the
lead
role.
Later,
STR
aka
Simbu
was
roped
in
but
the
actor
turned
down
the
project
just
before
the
thriller
was
about
to
kick
start
a
week
later.
When
the
script
was
narrated
to
Jiiva,
he
had
no
clue
that
he
would
be
essaying
the
lead
role
as
the
announcement
of
Simbu
doing
the
project
was
already
made.
It
is
also
said
that
he
had
asked
the
director
of
the
movie
about
how
his
character
has
been
given
so
much
of
importance
than
STR,
to
which
Anand
responded
that
he
would
be
replacing
STR
in
the
movie,
to
play
the
lead
role.
The
Antagonist?
In
the
beginning,
Sasikumar
was
approached
to
essay
the
villain,
but
for
reasons
unknown,
the
actor
didn't
take
up
the
role.
Narain,
Unnale
Unnale
actor
Vinay,
and
Ganesh
Venkatraman
were
also
few
who
were
considered
for
the
role
before
Ajmal
was
zeroed
in
for
the
role
of
Vasanthan
Perumal.
The
Remarkable
Music
Composition
The
romantic
songs
from
Ko,
Ennamo
Yeadho
and
Venpaniye
didn't
take
much
time
to
win
millions
of
hearts
and
are
still
favourites
of
many.
It
is
said
that
the
music
composer
Harris
Jayaraj
didn't
want
to
work
for
the
film,
as
he
felt
the
story
was
a
cliché.
But
later
the
music
virtuoso
accepted
the
offer,
and
yet
again
cast
his
magic
after
the
successful
hit
Ayan
directed
by
KV
Anand.
The
Story
And
Filming
Having
worked
as
a
photojournalist,
Anand
didn't
take
things
for
granted.
He
didn't
want
a
set
to
be
erected
for
the
film.
To
give
more
life
to
the
characters
and
the
story,
a
daily
newspaper
office
was
used
for
the
shooting.
Also,
the
movie
was
supposed
to
be
a
rom-com
drama
before
turning
it
into
a
mass
thriller.
Ko
also
became
the
first
Tamil
movie
to
be
shot
in
Norway.
The
movie
featured
an
ensemble
cast
of
Karthika,
Piaa
Bajpai,
Prakash
Raj,
Kota
Srinivasa
Rao,
Achyuth
Kumar,
and
Bose
Venkat
in
pivotal
roles.
Ko
was
bankrolled
by
Elred
Kumar,
Jayaraman,
Haresh
Vikram
Vijaykumar,
and
Udhayanidhi
Stalin.
A
sequel
to
the
film,
Ko
2
was
released
on
13
May
2016
with
a
different
crew
and
cast,
directed
by
Sarath.
