Actress Malavika Mohanan is set to make her Telugu debut opposite Prabhas in the upcoming horror-comedy 'The Raja Saab'. The film, which has been in production for several years, is slated for release on January 9. While advance bookings are currently progressing slower than Prabhas' recent action films like 'Salaar' and 'Kalki 2898 AD', expectations are that sales will increase as the release date approaches.
