It is not unusual for a filmmaker to take inspiration from a huge blockbuster of yesteryear and model his/her own story in the same fashion. We have seen many do so and SS Rajamouli is not an exception.
He likes many stories from our mythology and did try to model his previous films on old blockbusters but narrated the story in his own style in an effective way to score a hit with every film.
For, #RRR he took, Karan Arjun as an inspiration it seems. According to few reports Jr. NTR and Ram Charan will be seen as friends in 1920’s and brothers in 2019, it seems. Also, there will reversal in their fortunes from early lives, it seems.
Karan Arjun is still seen as the ultimate multi-starrer and it made SRK and Salman biggest box office stars, friends too. Let’s see how SSR version will come out!
