I remember when I saw this earlier on in the beginning of my deep dive into HK cinema(probably around the late 90'sor immediately after). I definitely didn't like it. I saw that Vinegar Syndrome gave it a re releases, so I decided to give it another chance. Undeclared War is a somewhat offbeat action thriller dealing with international terrorism towards the end of The Cold War. A eclectic international cast that has Danny Lee, Rosamond Kwan and Vernon Wells(from Commando, Road Warrior) in multiple uncanny roles here. The film is very dark in tone and actually has a lot of relentless action. I think this was done well, but feels a little uneven as film. I think Undeclared War has it's flaws. I don't think this is close to as good as something like City On Fire, but it easily is as good as a JCVD vehicles like Maximum Risk or Replicant. Undeclared War is a bit more unpolished and gritty than that and that's a part of it's charm.
