Actress Nushrat Bharucha of "Pyaar Ka Punchnama" (PKP) fame, says she and her co-star Kartik Tiwari, both had to shed all colours of PKP for their upcoming film "Akaash Vani".

PKP had got so "ingrained" in them that they had to "take it out and then enter this film," Nushrat said here Monday at a promotional event for the movie.

"More than efforts, it needed time and we had committed as much time to Luv sir (director Luv Ranjan) as needed," she added.

PKP saw Kartik as Rajat aka Rajjo while Nushrat played his nagging girlfriend Neha.

"(We said) Take as much time as you want, but let's make the right film. It should not make people say that she is same as Neha and he is the same Rajjo," she added.

And Kartik too feels that their characters are very different from what they played in "Pyaar Ka Punchnama".

"Her character Vaani and mine Akaash are very different from Neha and Rajjo. My character is very shameless, hers is very sweet. (In PKP) Neha was bitchy and Rajjo was an easy going boy," Kartik said.

"Akaash Vani" hits the theatres Friday.
