Actress Moushumi Chatterjee said actor Amitabh Bachchan "struggled a lot" and became "big" after a lot of hard work. "But I won't say if he became big for the better. When you receive so much, you behave very differently. You won’t even be able to think about helping others," the 76-year-old added. Amitabh and Moushumi worked together in 'Benaam'.
