Brothers AT arms.
This film is one of the four staples of John Woodom. It goes further than an action film with a deep story evolving around three characters, where all of their choices result in consequences of the others. This film has been out of print for decades and quite a difficult find at a reasonable price in the U.S. but I would not hesitate to pick it up if you do find it. You will be awed with Woo's fantastic storytelling, symbolism, action and effects. Witness the birth of the modern action film, and the showcasing of the Beretta 92 (Yeah, Die Hard did neither of those first, this is the original) A Hong Kong action masterpiece with not a moment of down time.
