Why did this director drop film with Nani?

No one wants to lose an opportunity work with Nani. But, Mytri Movie Makers had to foregos a project with Nani. Director Kishore Tirumala came up with a storyline, but Nani has been suggesting many changes.

Despite all the changes, Nani is said to be still not satisfied. Now, they are doing the same film with Saidharam instead of Nani. We are yet to know when the project gets going as Saidharam has KS Rama Rao film on hand and lined up Gopichand Malineni film after KSR project.
