Thnaks for everyone who posted their comments. I would appreciate If Arjay uncle fulfill his promise. the movie you mentioned "Garam Hawa" I tried to find this everywhere but all in vein.
As far as Pakistani movies are concerend, It is true that No paki movie is based on real Partition subject. I remember one of the Pakistani movies name "Khak or Khoon" written by Nasim Hijazi was very well picturised.
May be most of you have seen this movie.
