Even as getting ready for the release of her comeback film 'Oru Nadigaiyin Vaakumoolam', Sonia Agarwal is also set to commence her next venture. Titled 'Achachamenna', the movie will be directed by the same Rajkrishna, who helmed 'ONK'.

"Rajkrishna is impressed with the acting skills and dedication of Sonia. Hence he decided to keep on board the actress for his next flick too. So is Sonia, who is comfortable working with the director," sources say.

Buzz is that 'Jithan' Ramesh, who did a cameo in 'Oru Nadigaiyin Vaakumoolam', will play the protagonist in 'Achachamenna'. "After Osthi, the actor has got a meaty role to play in this new project," sources add.

It is said that 'Achachamenna' too will be based on real life experiences, quite like 'Oru Nadigaiyin Vaakumoolam'. "However, Achachamenna will not deal with affairs in the tinsel town. It will be a different entertainer."
