Bollywood actress Manisha Koirala is making her comeback in film industry with Sanjay Dutt's biopic. In the film, she will be seen playing the role of his mother Nargis Dutt. The actress says after her cancer treatment, she used to look like an alien as she lost her hair. Manisha was asked as being an actress, did she get worried about her look after chemotherapy?, She answered, "I knew about my hair loss, but was not sure of my look. At times, after surviving from a disease like cancer... people's look changes. All I knew was that I had to mentally prepare to fight it and I got a huge support from my family. After my chemotherapy, I lost my hair, eyebrows, and lashes. Looking at the mirror... I felt like an alien." About bagging the role of Nargis Dutt, Manisha said, "Though I wanted to get back to work, I was nourishing my body and focusing on my health as chemotherapy damaged some of my body cells. I was in Nepal then, when I got a call from Rajuji (director Rajkumar Hirani). He told me about the film and my character." About preparing for the role? She said, "I watched a documentary. I am watching her (Nargis Dutt's) films again and again and talking to (daughter) Priya Dutt a lot to know how she was in real life, her body language, how she used to talk, smile. I'm trying to get all the nuances right."
