Work on Tamil film Rum, being directed by Sai Bharath and featuring Hrishikesh, Sanchita Shetty, Miya, Vivekh and Narain, began in the city with a simple pooja on Monday. The film is being produced by All In pictures, the firm that produced Masala Padam (2015). Sources claim that the film will probably be the only ‘Heist-Horror’ Tamil film in recent times. Another reason why the film has been garnering interest is because it will have music by Anirudh. “This will be the first time that Anirudh will compose for a horror film,” says a source close to the unit.
