Cameo roles in films is become a fashion these days. There are few advantages of this - it doesn't require more than a day to shoot and most of the actors do cameo for filmmaker friends. But who are not friends they take a good amount of money for it. Like, Aishwarya Rai got Rs 50 lakh for 'Shakti' and Madhuri Dixit got the same for the title song of 'Bade Miyan Chote Miyan'. Shah Rukh Khan done cameo free in Shakti, because he don't wanna turn down Sridevi and Rani Mukherjee done cameo roles in Karan Johar's films just only for friendship.
