Mumbai, Aug 18 - Kangana Ranaut is known for playing heavy duty roles in films like 'Gangster' and 'Fashion', but the actress has now signed on her second light-hearted movie 'Tanu Weds Manu'.

The fun film, directed by Aanand L. Rai of 'Strangers' fame, has Kangana paired with R. Madhavan.

'It was after much deliberation that Kangana was finalised for the role. The character that Kangana would be playing in 'Tanu Weds Manu' is such that it is of paramount importance to get the casting right,' Rai told IANS.

Kangana, who has played a traumatised women in most of her films, was signed on for her first comic role by Anil Kapoor for his production 'No Problem', a comedy directed by Anees Bazmee.

Before venturing into comedy, Kangana did a series of serious films.

While she was haunted by ghosts in 'Raaz - The Mystery Continues', 'Fashion' had her playing a supermodel who fell to drugs and abuse. 'Life In A... Metro' showed her in a turbulent affair with a much married boss (Kay Kay Menon), 'Woh Lamhe' had her play a schizophrenic while in 'Gangster' she played an alcoholic moll to a gangster (Shiney Ahuja).

Director Rai, however, is confident that she will pull off the role in 'Tanu Weds Manu'.

'Yes, I have studied her filmography quite closely and I know for sure that 'Tanu Weds Manu' would finally showcase Kangana in a different light. There is a definite humour to the film which thankfully is poles apart from life vs death roles that Kangana has played in the past,' he said.
