After
Raanjhanaa,
Dhanush
waited
for
about
eight
months
and
went
through
some
33
scripts
before
Shamitabh
happened,
which
he
feels
is
the
toughest
role
in
his
career.
"A
lot
of
scripts
came
my
way
after
Raanjhanaa.
I
think
I
read
about
33
scripts
but
there
was
nothing
solid
to
back
up
my
first
Hindi
film.
I
kept
waiting
for
about
eight
months
when
R
Balki
called.
He
is
like
'if
you
are
free
for
a
couple
of
hours
do
drop
in'.
After
a
two-hour
narration
I
knew
I
was
doing
it," Dhanush
told
in
an
interview.
The
31-year-old
actor
believes
Shamitabh
is
a
great
opportunity
for
him
to
learn
from
the
best.
"It
would
be
my
toughest
role
in
my
28
films
career.
It
was
mentally
very
taxing.
The
character
was
not
easy
to
play.
Hopefully,
I
have
done
a
convincing
job
and
lived
up
to
the
director's
expectations
and
people's
expectations
if
they
have
any," he
said.
Dhanush
is
sharing
the
screen
space
with
Amitabh
Bachchan
and
newcomer
Akshara
Haasan
in
the
film,
which
is
slated
to
release
this
Friday.
When
asked
about
his
biggest
challenge
while
facing
the
camera
for
Shamitabh,
Dhanush
said
he
just
wanted
to
be
able
to
do
justice
to
Bachchan's
voice.
"It
was
a
great
opportunity
to
learn
from
the
best
and
I
tried
to
absorb
as
much
as
possible.
I
was
nervous
only
because
handling
the
majestic
voice
of
Amit
ji
is
not
easy.
I
was
worried
whether
I
will
be
able
to
carry
his
majestic
voice
in
my
small
frame," Dhanush
said.
It
is
a
busy
month
for
the
actor,
who
has
a
very
successful
career
in
Tamil
cinema,
as
he
will
start
promoting
his
next
Tamil
film
Anegan
before
beginning
the
shoot
on
Maari.
