Those Games of death films are really just the tip of the iceberg when it comes to "Bruceploitation". Some of the films and stars during that "bruceploitation" period seem almost ridiculous in trying to fill the void which was created after Lee's death. Chinese cinema was in major trouble. It took a while before Jackie Chan emerged. Still, for the sake of deleted scenes and whatnot, Game of death I and II are essential films for any Bruce Lee fan out there. Note that the funeral of Billy Lo is actually the real funeral of Bruce Lee.

Anyways Irishman, you are far from watching all of his movies; those 6 movies are the easy part - now try and get hold of his movies from the 40's and 50's when he was just a boy

But if you got TCM - I'm sure you can catch "Marlowe".

Anyway, you want some Chan recommendations:

-Well, there's the classic "Drunken Master" - a must-see for every Chan fan out there. His first major hit and still a cult film to this very day. You can start with that one.
(BTW you've already seen him in "Enter the dragon" - but that was a small part)

-There's the very famous "Rumble in the bronx" - its a fun movie, I think you'll like it. The plot BTW is said to be based on Bruce Lee's "Way of the dragon".

-Then you got the Police Story series. The 4th is the most popular and rightly so. Also my favorite Jackie Chan film. The full title is Jackie Chan's First Strike (PS4). What I really dig in this film is the outstanding choreography of the fights. Awesome stuff there. Plot is secondary, as usual with his films, but who cares about that?

-Need I tell you of the "Rush Hour" films? probably not. Still, I highly recommend the first, the second was not as good, but still y'know. And I think they're filming a third one right now.

-There are really lots o other films, tho some are harder to get, but I think that should give you a good start.
