The "ORG 5.1" notation likely refers to the audio format, which is a 5.1 surround sound setup. This provides an immersive audio experience with five full-range channels (left, center, right, left rear, and right rear) and one subwoofer channel.

The quality and file size of the movie may vary depending on the source and encoding settings. A typical Blu-ray or HD version of the movie can range from 5-10 GB in size.

You can find the movie on various online platforms, including streaming services and torrent websites. However, I recommend checking legitimate sources like Amazon Prime Video, Google Play Movies, or iTunes for availability.
