The actress first appeared in Sujoy Ghosh's fantasy drama Aladin before bagging her breakthrough role in Mohit Suri's psychological thriller Murder 2.
"I am a more confident actress today. The change is definitely inevitable. It needs to be there, you need to grow. So that's why I am looking forward to a lot more challenging roles today than ever before," Jacqueline told PTI.
The 31-year-old actress has worked in big films like Race 2, Brothers, Housefull 3 and the Salman Khan starrer Kick.
Asked if directors have not tapped her full potential as an actress, Jacqueline said, "Possibly yes. I don't know if directors haven't tapped into it but maybe, I wasn't ready before. Now I do feel ready to take on more challenging stuff.
Earlier, I think I probably had not given enough (in my roles) because I wasn't ready for them."
The actress, who recently starred in Dishoom is set for her next, A Flying Jatt.
Jacqueline feels her perspective towards the craft of acting has changed and she is willing to contribute a lot more than what she used to earlier.
"Now, the kind of roles I do and the films I take on, I look at them in a different way. The perspective has definitely changed. I am enjoying the process. So from now on, I will give them a lot more so then it helps even the directors a lot."
"A Flying Jatt" will feature Jacqueline as the love interest to Tiger Shroff's character of a superhero. The Remo D'Souza-directed superhero-action movie is scheduled to release on August 25.
