Mammootty,
the
big
M
of
Mollywood,
is
all
set
to
play
his
legendary
character
Sethurama
Iyer,
once
again.
The
actor
has
finally
given
a
green
signal
to
play
the
lead
role
in
the
5th
part
of
CBI
series.
Sethurama
Iyer
is
undoubtedly
the
most
popular
detective
character
ever
made
in
the
history
of
Malayalam
Cinema.
The
first
part
of
CBI
Series,
Oru
CBI
Diary
Kurippu
released
in
1988.
The
movie
was
followed
by
3
sequels.
The
second
part,
Jagratha
was
one
year
later,
in
1989.
Sethurama
Iyer
was
a
surprising
character
for
the
Malayali
audiences,
who
were
only
familiar
with
the
heavily
macho,
rough
and
tough
police-detective
characters.
Even
though
the
first
two
parts
were
huge
successes,
it
took
15
years
for
director
K
Madhu
and
writer
SN
Swami
to
come
up
with
the
part
3,
Sethurama
Iyer
CBI.
The
fourth
part,
Nerariyan
CBI
was
released
in
2005.
The
character
Sethurama
Iyer
was
originally
written
for
Mohanlal.
But
the
actor
turned
down
the
offer,
as
he
felt
that
the
movie
lacked
the
commercial
elements
needed
for
a
crime
thriller.
Later,
Mammootty
was
roped
in
for
the
role.
As
per
the
latest
reports,
all
the
major
characters
of
CBI
Series,
except
Jagathy
Sreekumar's
Vikram,
will
appear
in
the
5th
part
as
well.
It
has
also
been
rumoured
that
the
5th
part
will
be
the
final
movie
of
CBI
Series.
