Why Pawan Kalyan sacked Sampath Nandi?

It���s well known that Sampath Nandi was originally supposed to direct the Pawan Kalyan-starrer, Gabbar Singh 2. The director even graced the film���s muhurat earlier this year. However, things
took a different turn and KS Ravindra (Bobby) eventually replaced Sampath as director. Here���s the inside story of what happened!
A source close to the actor reveals, ���More than a year ago, Pawan penned the plot line and asked Sampath to develop it.Since then, the director has been working constantly on the script.The filmmaker even flew down to Spain (during Attarintiki Daredi shooting) and narrated the subject to the actor. Pawan however, wasn���t impressed and suggested a few changes.Later, the director even flew to Goa (where Pawan was cooling his heels) to narrate the script, but once again, the actor wasn���t pleased with the way it turned out���.
With time passing by, rumours gained momentum that the film was shelved and Pawan was under pressure to quash them.Eventually, he rolled out the action entertainer even while work on the script was going on.
���Sampath���s narration wasn���t reaching the expected standards of the Power Star and in a dilemma, contemplated a replacement.With further delay to the project, Pawan sensed that the film may
not go on floors soon; so he decided to sign Gopala Gopala���, adds the source.
Meanwhile, Jayanan Vincent, the cameraman for films like Gabbar Singh, Teenmaar, Gopala Gopala, Power, and a close aide of Pawan, approached the actor and referred Bobby���s name. The actor spent quality time with the director, who gained confidence of the actor with his impressive narrative skills. Pawan immediately okayed Bobby���s name. Sampath was out and Bobby walked in, and the rest is history!
