Right now the date is 1984...
According to:

http://www.movieworld.com.hk/zine/Offic ... a-en.shtml

The movie was released in 1985....Anybody have any reason to keep it at 1984?

The Shaw Screen confirms your suggestion. According to the book the movie has been released on 5 January 1985, so the release date showed on Movieworld.com is correct.
