I haven't seen this film and I'm not even sure it belongs here but, uh, the title indicates there's a chance it might. LOL.
Cast info and review lifted from IMDb:
Directed by: Phillip Ko & Siu Gwong Yeung
Cast: Marcus Fox,Phillip Ko, Kit Ying Lam, Siu-Ming Lau, Alex Man, Ben Ng.
The Phantom War (1991) was an early star vehicle for Ben Ng. He stars as a shell shocked veteran who's past keeps on haunting him. No matter how hard he tries to forget his traumatic years in the army, there's always someone or something that reminds him. During the past few years, Ben has been trying to rebuild his life. Everything is going along fine until he learns about a soldier from his company who still has an unsettled grudge with Ben. What's a crazy war vet going to do? Does he take this "new" threat from his past lying down or will he do something about it? Hardcore stuff from a future category III villain.
