T-Series and Ellipsis Entertainment's recently announced comedy, 'Tumhari Sulu', has already rolled out its pre-production.

Vidya Balan, who is all set to play a radio jockey (RJ) of a late night radio show, has started prepping. A diction coach has been appointed to train Vidya to perfect her character of Sulochana (a.k.a. Sulu), a housewife who lands up with the unpredictable job of entertaining lonely callers.

The film is being directed by noted ad filmmaker Suresh Triveni, who said, "Middle-class housewives have been portrayed as hassled and troubled in Hindi films, but I'm a huge Hrishikesh Mukherjee fan and he showed that even middle-class families can be happy. I want the audience to walk out with a big smile on their face." On the appointment of a diction coach for Vidya, he said, "I need her speech to have a new flow. It`s not tapori Hindi at all but the kind one hears in the ladies` compartment of a Mumbai local train."

He adds, "Her look will be Indian but trendy. Her night show has a huge element of mischief. It`s a Vidya you haven`t seen before. We are currently auditioning a host of actors for the male lead."

The shooting of Tumhari Sulu` will take place in Mumbai from April. The film is set for a December 1 release. It is produced by Bhushan Kumar, Krishan Kumar, Tanuj Garg, Atul Kasbekar and Shanti Sivaram Maini.
