Gautam Menon is not a "Great" director... He still needs to get there.. Vinnaithandi Varuvaaya was not a "Great" film to have a Hindi remake "Ekk Deewana Tha"... Minnale was a good film & so was "RHTDM" but it wasn't something you say "never seen before as far as Hindi audience go... remember Hum Kisise Kum Nahin (1977)."
Puttanna Kanagal is a legendary great director, he didn't succeed in Bollywood with a film which we Kannadigas call a masterpiece. Just because that film flopped in Hindi doesn't mean the Kannada version was not a masterpiece.
Hirani made 3 Idiots... Did you forgot Shankar remade it as Nanban & made it a Hit on his own terms despite 3 Idiots being the biggest hit at that time?
And they do have the balls to spend 150cr+ on their films & they're intelligent enough to know the industry politics. A bollywood talent cannot survive in south because it's our right to destroy any chances of that talent succeeding. Why? Because that's what Bollywood does to our talents. They didn't let Kamal Haasan grow in Bollywood... He took away all the credits for Saagar, stealing limelight from Rishi Kapoor & that's all it took for Bollywood to eliminate Kamal. Shankar tried entering Bollywood with Naayak, one of the most watched & appreciated movie on tv but just go through how much trouble the movie went & how tactfully the Bollywood industry made sure Nayak wouldn't be a success.
Baahubali was supposed to be in Hindi too... Makers got clever that's all.. Why question Shankar or Rajamouli.. Does Bollywood directors have the balls to come down to south & survive the competiton, no matter who he is? We've plenty of south Directors who dominated Bollywood once upon a time, how many Bollywood directors made it in the south, forget even dominating?
