Sorry, should have posted this in here...
I hate to contradict Tang, but the U.K. FIRST release dates for Bruce's films are:-
The Big Boss 12-2-74
Fist of Fury 22-11-72 BBFC, OR 20-7-73 IMDB...?
Way of the Dragon 15-2-74
Enter the Dragon 23-10-73
Game of Death 26-4-78
I think most are spot on, but the BBFC saying 22-11-72, and the IMDB saying 20-7-73, for Fist of Fury, neither seem right to me, as I remember it was released after Enter, so sometime early 74 for the U.K. release would be more likely...
