Omar Vandal and Zakir Thaver met in college, and after many discussions on Pakistan and its achievements, they developed a great interest in the life of the country's only Nobel laureate Dr Abdus Salam.

Their interest turned to passion and they spent the last few years researching Salam, whose "personal life and his contributions to the world of theoretical physics tell a remarkable tale," Vandal and Thaver said.

The video below features some of the unseen footage, interviews and archival pictures used in their documentary which is scheduled to be released soon.
