"All of Chopra Sahab's films reflected the refinement that his fine academic background gave and the sensitivity that an eventful life gifted him with," Dilip Kumar said in a statement issued here.
The legendary actor described Chopra as "more a friend than a producer or director when we worked on the films which brought us together".
Chopra died at 8.15 a.m. Wednesday at his residence in suburban Juhu. He was 94.
Dilip Kumar said Chopra was always open to discussions and he spelt out the nuances of the story, characters, situation, with clarity and precision.
"About characters, he was especially analytical and explorative," Dilip Kumar said.
He recalled the time they spent together at Chopra's house, sharing views on various aspects of filmmaking.
"It was always invigorating for me as an actor because he always appreciated the fact that I needed to delve into the sensibilities of the character I was rendering," he explained.
Chopra's classic blockbuster "Naya Daur', portraying the battle of man versus machine, was mostly shot at outdoor locales. "Chopra Sahab made them like picnics, he was engagingly witty at times and full of quotes and anecdotes about great political or literary personalities," said Dilip Kumar.
