The bluray of Enter the Dragon is well worth getting. The picture quality is very good and I haven't noticed any of the sync problems that a few people have commented on.
The film itself is essentially a Bond martial arts movie, but without the gadgets. You get the meglomaniac on the Island, the cat, and Bruce Lee is effectively Bond. However the martial arts in this film were all choregraphed by Bruce Lee and they are the best things about the film. I can't be certain but most, if not all, the fight scenes appear to have been done without wires. You also get some classic Bruce Lee sayings in the film such as "the art of fighting without fighting", "move like water" etc. The other main actors are also good and there is a nice line in humour occasionally.
Amongst the extras are some fascinating facts. For example in the fight with Bob Wall, when he lunges at Bruce Lee with the broken bottles, they were using real bottles, and in one take Bruce Lee mis-timed his parry and ended up with a lot of stiches in his hand.
Now that you can get this for under a tenner its well wortg replacing your DVD.
