Everybody
knows
that
Karan
Johar
is
a
terrific
filmmaker
but
not
many
know
that
he
also
acts.
He
had
earlier
appeared
in
films
like
Dilwale
Dulhania
Le
Jayenge,
Main
Hoon
Na,
Om
Shanti
Om,
Fashion
and
Luck
By
Chance.
Once
again,
he
is
going
to
do
a
cameo
role
in
Jaane
Kahaan
Se
Aayi
Hai.
Director
Milap
Zaveri
said
that
he
was
kind
enough
to
shoot
his
part
while
he
was
doing
interviews
for
My
Name
is
Khan
at
Mehboob
Studios.
He
added
that
they
needed
a
noted
director
to
say
some
few
words
of
praise
for
actor
Ruslan
Mumtaz,
who
plays
a
superstar
in
the
film.
They
have
already
shot
with
Farah
Khan
and
Karan
has
done
his
part
too.
Producer
Nikhil
Advani
is
also
planning
to
rope
in
Katrina
Kaif
and
Deepika
Padukone
for
cameo
roles
in
the
film.
They
would
play
themselves
in
the
film.
Akshay
Kumar
also
plays
a
small
role.
Besides
these
actors,
the
makers
of
the
film
are
planning
to
rope
in
many
more
actors
for
cameo
roles.
They
have
already
approached
many
of
them
and
are
looking
forward
to
receive
positive
signal.
