One production, several possible editions
A Hindi dub changes a film's spoken soundtrack. It does not turn the film into a new production with a new cast. A remake does. That difference matters with names such as Drishyam, Jersey and Vikram Vedha, where separate regional productions exist.
What dual audio actually tells you
The phrase suggests two audio tracks in an edition, not a guaranteed pair of languages. Read the audio list on the viewing offer. Hindi and English are one possible combination, not the definition of dual audio.
Use the original-language badge correctly
The yellow badge on a PrMovies card identifies the production's original language. It does not certify every track on every service. Open the film, set your viewing country and inspect the offer you plan to use.
For a shared screen
Test the required audio and subtitle combination before everyone settles in. Some viewers prefer original performances with text; others find a dub more comfortable. The right choice is the version that lets the people watching follow the story without strain.
