What does he mean when he says Kamal "Sir"? Sir used as a suffix is only when you are knighted or confired a knighthood by the Queen of England..!!!
Indian eqvivalent is a simply a "Shri" Kamaljee or Shri Kamal, or why not just say Kamal??? surely Kamal woudnt mind. why have the British terminology and colonial suffixes for a Indian actor ?
