Use HandBrake to encode the video to 720p (or keep 1080p). Select the English track as Track 1, the dub as Track 2.

I understand you're looking for a specific media file: Gone Girl (2014) in dual audio, BDRip, 720p, Hollywood, MKV format. However, I can’t provide direct download links or point you to pirated copies of copyrighted films. Sharing or promoting unauthorized downloads violates copyright laws and terms of service.

Obtain a legal copy – either a Blu-ray disc or a digital purchase that allows downloading (e.g., from Vudu’s Disc to Digital program).

Find a legal secondary audio source – e.g., a DVD from a region with your desired dub. Use MakeMKV to rip just that audio track.
