Been watching Bits and Pieces of Duke of Mt.Deer 1984 since I’ve been rewatching Duke of Mt.Deer 1998 version. Tony Leung is freaking awesome as Wai Siu Bo in Duke of Mt.Deer 1984 but I prefer the Noel Leung as Ah Ke in Duke of Mt.Deer 98 version. Overall I liked Tony Leung in Duke of Mt.Deer 1984 but I prefer Steven Ma as the Emperor Hong Hei and the wives, and the comedy in the 1998 version.
Both Duke of Mt.Deer 1985 and Duke of Mt.Deer 1998 are good. If you prefer to watch in depth relationship between Siu Bo and the emperor, watch the 1985 version. If you prefer comedy, watch the 1998 version.
