re: -HUMSAFAR-
then you’ll be surprised at how well he spoke Urdu in Dastaan which was based around the time of partition so there were no English dialogues in it whatsoever. In Humsafar you can sense a hint of a Punjabi accent here and there (I am not saying that’s a negative just for comparison) but in Dastaan his Urdu diction was impeccable!
