Ugh he is such an egoistic man!

its unprofessional to walk out like this 

but Bollywood stars usually show their egoes 

they consider themselves superior to regional stars and directors 

better to take a south star only why run after bollywood stars

anyways south stars many of them have better acting skills than amir khan or anyone else and less ego  

only thing they are bad at pr like amir, srk etc prs campaigns is where they fail 

in south director is like school principal no matter its rajnikant they have to listen to director unlike bollywood where hero is the overall authority
