'Khallas' girl Isha Koppikar is gearing up for Bollywood comeback after four years, with debutante director Ankur Narendra Bhatia's 'Saangli'. The movie moves along the line of a female spiritual leader and her mentor, who will be played by Isha. “The film travels from 1960s to the present day and Isha's role spans from 30 to 80 years,” said Bhatia. The 38 year old actress who is married to restauranter Timmy Narang, delivered a baby girl last year. She has had her fill of colorless roles and was on the lookout for something more challenging in the last three years. “Acting is my passion and cinema is in its best phase today with different kind of films being made. I think this is a good role to begin with,” she smiles.
