Proving his versatility, Chopra on one hand directed intense dramas "Deewar", "Trishul", and "Mashaal", while on the other he made family sagas like "Parampara" and thrillers - "Kala Patthar" and "Darr".
His movies were sometimes based on real life tragedies. The Dec 27, 1975, accident in a coal mine in Chasnala near Dhanbad inspired the multi-starrer intense drama, "Kaala Patthar" starring
Amitabh Bachchan, Shatrughan Sinha and Shashi Kapoor.
Chopra was one of the few filmmakers who created a cult following for his actors -- Amitabh Bachchan,
Sridevi and Shah Rukh Khan - and gave audiences evergreen songs.
