The original choice of casting for recently released "Oopiri" was Nagarjuna, NTR Jr and Shruti Haasan but NTR rightly opted out from the film because his image would hinder the movie's beautiful message. After the release of the movie, everyone is agreeing with his view.
In the case of Shruti Haasan, it is a loss for her. Although Tamannah doesn't have a very important role in the movie as the film primarily focuses on Nagarjuna and Karthi, Tamannah is also getting good praise because of the story.
Shruti Haasan joined the shoot of "Oopiri" for few days, then walked out of saying she has issues of adjusting dates.
But back then gossips did rounds that she felt her role is not big enough in the movie, so she opted out of it. While now it is Shruti's loss and Tamannah's gain.
PVP and Shruti are now not on talking terms because of this incident. The team is said to have vowed not to take her in any of their future Telugu or Tamil productions.
