Kangana Ranaut - Our queen of Bollywood once admitted that "People in the industry treated me like I didn't deserve to be spoken to and I was some unwanted object. I couldn't speak English fluently and people made fun of me for that. So dealing with rejection became a part of life."
Govinda - He certainly knows English, but can't speak fluently. Actually, it doesn't matter when you are so popular for your acting. All that matters is your work.
Akshay Kumar - Recently, he announced that he feels more comfortable to talk in his official language, Hindi. We should be proud of our national language. However, it seems like he was just trying to cover his bad English. But, no matter what we are proud of you Akshay.
Rajinikanth - He was born in an ordinary family and after completing his school education he did various odd jobs like bus conductor, carpenter and coolie. He never got a chance for higher studies or to learn English. He is fluent in Tamil and went on with his unique style in Bollywood and South movies.
