A source close to the director reveals, "Rakesh Roshan had written portions of Krrish along with other writers. The movie starring Hrithik Roshan turned out to be a major hit. He does not want the sequel to be any less. The director sat down almost two years back and was penning down the script to Krrish 3. But to his surprise, Spiderman 3 which released then had the same plot as he had crafted out."
The source continues, "At that point, Rakesh Roshan kept the script back into his drawer and started working on his production Kites. Now that Kites is almost done and will be releasing soon, Rakesh has gone back to re-working on the script of Krrish 3. The director has hired freelancers too, to help him make alterations and the required inputs for the film. He wants a new plot, and does not want any similarity to the Spiderman movie plot."
"In the past Rakesh Roshan has paid a heavy amount to a young composer Ram Sampath who went to court saying that Rajesh Roshan, composer of the soundtrack for Krazzy 4, sampled his music from the Song Erickson Thump ads in the songs Break Free and Krazzy 4. Ram won the case and was given a whopping amount. To avoid any such troubles, Rakesh Roshan is extremely cautious," adds the source.
