Again, we're sharing this because it's legal and it's on YouTube.
There may be totally illegal ways of procuring movies online and we're not - for one single, solitary second - promoting that. We're talking about this because it's on YouTube and it's legal, and, y'know, Stargate is really underrated and definitely one of Roland Emmerich's best film - if not his best, in fact.
Kurt Russell plays a hard-ass Air Force Col. Jack O'Neil who, after a bout of suicidal depression following his son's horrific death, volunteers to enter a mysterious portal that could send him to the other side of the galaxy - and possibly never bring him back. It was a huge blockbuster in the '90s, featured '90s James Spader, and had tons of eye-popping special effects.
In short, it's a blast - and you can watch it for free on YouTube. Enjoy!
