Concept:
Tracking the historical release timeline of benchmark Indian films reflects structural shifts in style, music, and cinematic presentation.
Step 1: Identifying the specific release years.
• Shatranj Ke Khiladi: Directed by Satyajit Ray, released in 1977.
• Dil To Pagal Hai: Directed by Yash Chopra, released in 1997.
• Gadar (Ek Prem Katha): Directed by Anil Sharma, released in 2001.
• Devdaas (Shah Rukh Khan version): Directed by Sanjay Leela Bhansali, released in 2002.
• Baajirao Mastani: Directed by Sanjay Leela Bhansali, released in 2015.
Arranging these from the earliest to the most recent release year gives the exact sequence E-D-C-B-A.
