"It is not based on anybody's life, it's a fiction. Yes, there are some similarities like it has a women's gang and the pink colour but the film is not a documentation of Sampat Pal's life. A lot of people took it for granted that it's about the gang but it's not," Sinha told PTI in an interview.
The 'Ra.One' director is turning producer with the film and admits that it was not an easy project to put together.
"Also I knew it would not attract money easily as it is not a usual film. I went through many tough times but ultimately I enjoyed making this movie," he added.
With 'Gulaab Gang', 47-year-old Sinha brings for the first time the two divas and former rivals -- Madhuri and Juhi -- on the big screen.
"We approached Juhi and she was surprised with what was being offered. She has never been approached with something like this before but it took her just three meetings to say yes.
