Devdas is NOT public domain. However, the original 1928 silent Devdas film is. If your search for "exclusive" mistakenly tags the 2002 version, you are looking at the wrong film. But the Archive does host rare TV recordings and interviews with the cast from 2002 that are officially abandoned by copyright holders (Orphan Works).
Amazon Prime Video hosts the official digital version of Devdas. While not called "exclusive," the Prime version is often the best mainstream stream: index of devdas exclusive
This is where the "Index" search pays off. Bhansali creates a world that does not exist in reality; it is a hyper-stylized Bengal of the early 1900s. Devdas is NOT public domain
Instead of typing only the keywords, use Google dorks (advanced search operators): Exclusive film elements
The irony? The "exclusive" 4GB file you find on an open index is often a screen-recording of a TV broadcast from 2003, upscaled poorly. It looks worse than the legal HD version on YouTube or Prime Video.
Before you click that link promising index of devdas exclusive, you must understand the risks. Open directories are unregulated. Here is what could go wrong:
Many "exclusive" files are .exe or .scr files named Devdas_2002_Exclusive.mkv.exe. Windows hides the ".exe" by default. You think you're opening a movie; you're actually installing a keylogger or ransomware.
