"After Tanu Weds Manu, people are much more confident about me and when they offered this role to me, I was very excited. It is totally opposite to what I have already done and tried," the 25-year-old said at the first look launch of the film.
"This is a girl who is not street smart, clever New Yorker. She is quite opposite to that. It's been a very good experience and I hope people like it," she added.
The 2011-hit Tanu Weds Manu was a romantic-comedy and she had teamed up with R. Madhavan in it.
When asked about working with an action hero like Sunny, Kangana said actors don't think the way audiences do.
"So our approach towards other actors is different as compared to what you guys mostly perceive us as."
"When I think of Sunnyji, I think of him as an actor and not as someone flying, doing all kinds of action, or punching people. For me, he is an actor and you get to see his different sides when he plays an action role or a romantic role," she added.
Co-directed by Radhika Rao and Vinay Sapru, I Love New Year is set for an April 26 release.
