If it’s on physical disc in one region but not where you live, it might be possible to purchase that disc and ship it to your home. While it might be region-blocked on the disc, there are ways to bypass that with certain disc players or converting them on your computer. The legality of bypassing region-blocking may vary depending on your jurisdiction, but from a technical standpoint it’s certainly possible. It’s probably less legal liability than going straight to piracy (especially compared to the liability from torrenting where they try to claim someone’s engaged in illegal distribution).
