It will feature actresses from different regions.
"Five different languages and five different top most heroines of their states are there. That's why we call it 'mummy item'," Sajid said.
"My first film came in 2007 - 'Heyy Babyy'. But I always wanted 'Himmatwala' to be my first film. I had been writing the draft keeping Ajay (Devgn) in mind. When I closed my eyes and imagined a poster of 'Himmatwala', I can (could) only think of Ajay," he said.
