A YouTube channel run by an archive (like the Kerala State Film Development Corporation or a private collector like Vintage Malayalam Movies ) has verified that the copy they are uploading is not a fake.

The "verification" becomes a disclaimer: "Yes, this is the real thing, but it's not what you expected."

The narrative of Mohanayanangal blends elements of rural superstition with psychological horror.
