Nandamuri Balakrishna, who is basking in the success of Dictator, has begun preparations for his 100th movie. The actor has been tapping various options and is contemplating to work either in a socio-fantasy or an historical drama. According to our well-placed sources, veteran writer Paruchuri Venkateswara Rao's son Paruchuri Ravindranath has readied a historical script to Balakrishna. Already, Ravi has narrated the script to the Simha actor and is waiting for his response. The film will showcase Balayya in a historical yet powerful avatar.
