Karthi is on a strict diet for achieving fit and slim look for his next film Kaali to be directed by Attakathi Ranjith.

Kaali is touted to be an action entertainer and the actor will be seen in a rough look. The actor has been hitting gym from sometime and has been on strict diet.

The actor was criticised for his bloated look in All in All Azhaguraja, and has now hit the gym with a vengeance. Ranjith wants him to look slim and mean for Kaali.

KE Gnanvelraja's Studio Green banner will be producing the movie. Catherine Tresa is expected to play the female lead role. Major portions of the movie will be shot in the slum areas of North Madras, as per the reports.

Karthi hasn't scored hits with the last two releases and the actor seems to be working hard for his upcoming projects. Karthi will promote his upcoming release Biriyani from December.

All the best Karthi, Nothing is impossible!
