I have been underweight all my life. And I lost about six kg. It was important to look the character primarily when I am playing a person who is not my age. I felt 50 per cent of my job will be done if I look the character. The film talks about the coastal history of Kerala, which spans over 30 years. There was a makeup artist on board and Mahesh Narayanan, my director, actually went through my grandfather’s images and that’s how we started working on the look. The most challenging part was to get the look in all three timelines. It is not just my character that went through this transformation, but every character in the film was based on three time periods. So, I had to collaborate with my co-stars and then crack it.
