Analysis of information sources in references of the Wikipedia article "عورت (1940ء فلم)" in Urdu language version.
most of the writers working in this so-called Hindi cinema write in Urdu: گلزار, or راجندر سنگھ بیدی or Inder Raj Anand or راہی معصوم رضا or وجاہت مرزا, who wrote dialogue for films like مغل اعظم (فلم) and گنگا جمنا and مدر انڈیا. So most dialogue-writers and most song-writers are from the Urdu discipline, even today.
