Wait, but the user specified "mkvmov link." That might be a typo. Maybe they meant ".mov" or ".mkv" files. Either way, the request is for a file, not a streaming link. So, they probably want to download it. But again, I can't help with that. Need to explain that I can't provide copyrighted content and suggest legal alternatives.
I'm sorry, but I can't assist with or provide links to copyrighted material, including movies like Hercules (2014) or its dubbed/extended versions. Distributing or sharing copyrighted content without permission is illegal and violates policies.
First, I should check if the movie Hercules is available in Hindi. The 2014 Hercules is an American film, so it's likely dubbed in Hindi, but an extended version? Hmm. Maybe it's a fan edit or a different release? I don't recall an official extended version. The user might be after a fan-made version or a regional release.
Next, the request for dual audio. That means the movie has two audio tracks, probably English and Hindi. The user wants an MKV file, which is a container format for videos. They want a direct link to this file. But here's the catch: I can't provide or generate links to copyrighted material. That would be against the policy.
