@ashcamp16 the script won't get the green signal without the approval of Akshay or Salman.
It's not like they signed & script got shuffled without informing. If shuffling has happened.
Sajid Nadiadwala is close to Akshay & Salman. Sajid considers Salman as his lucky charm anyways.
Farhad Samji didn't start overnight. The Sajid-Farhad duo started as lyricists. Then got promoted as film writers. It's Rohit Shetty who brought them all the fame actually having directed most of the films writtien by them - Sunday, All The Best, Golmaal 3, Singham, Bol Bachchan, Chennai Express... Dialogues for Singham Returns, Dilwale, Golmaal Again & Simmba.
If somebody has made it in the industry even after doing Ram Gopal Varma Ki Aag very early in their career, then they have to be commended, irrespective of individual perspective on their work. And even after Himmatwala, the career is still going strong, the success has always found it's way in.
