City on Fire is one of the best Hong Kong Movies from the 80s. Chow Yun Fat is the main reason why this movie work, His performance is amazing , the Co lead Danny Lee ( Known from The Killer) is also great in his Supporting Role as one of the Gangsters., though this Movies is sometime a bit slow it has a great atmosphere. The Showdown has really some similarities with Reservoir Dogs and there are some Bloody Shootouts. I can recommend this Crime Thriller with a great Chow Yun fat.
Tip : Watch the Short Movie "Who Do You Think You're Fooling?" It's on Youtube about the similarities between this Two Movies (City on Fire , Reservoir Dogs)
