The actress played an introvert Delhi girl in the coming-of-age drama directed by Vikas Bahl that garnered her the best actress trophy at this year's National Film Awards.
"Filmmakers do have a tendency to typecast in Bollywood.
Ever since I did 'Queen', I am getting similar scripts. It is true that they think I can do this best," Kangna said.
Back on the screen with the sequel to her 2011 hit "Tanu Weds Manu", the 28-year-old actress believes she has carved out a career by playing difficult roles.
"Every performance is difficult. My roles are never easy.
Even a small role in "Krrish 3' may not have been emotionally challenging but it was physically tiring. 'Queen' and 'Fashion' were emotionally testing. Similarly, it was emotionally draining to play two characters in 'Tanu Weds Manu Returns'."
In the Aanand L Rai-directed film, R Madhavan will also reprise his role from the original. The movie will hit theatres on May 22.
When asked if the four-years gap between the release of the first film and the sequel will have any adverse impact, Kangna said, "We kept that in our minds. Kids who were nine or ten during the release of the original film are 15 and our major audience now. It is a family film.
"It is not important to watch the first film to understand what happens in 'Tanu Weds Manu Returns'. It is about two people- a husband and wife, who are completely different."
Kangna said the upcoming movie is about what happens after the two lead characters marry and is not a comment on modern and contemporary marriages.
"It does not say anything about the institution of marriage. It is about things which are intangible in a marriage. The story is about the love between the two characters," the National Award winning actress said.
