lol, wtf were they thinking anyway, they effectively made it so that two different Bruce Lee films have the same name (in different versions etc)!!!
I heard they originally wanted to rename ‘The Big Boss’ as ‘The Chinese Connection’ (because The French Connection was such a hit, and both films have drug theme) but they accidentally mixed tapes and that’s how ‘Fist of Fury’ became ‘The Chinese Connection’ and ‘The Big Boss’ became ‘Fist of Fury’. When they noticed their mistake, it was alredy too late. They had to make some difference between the names, so they decided to add “s” to ‘Fist of Fury’, therefore ‘Fists of Fury’.
After ‘Enter the Dragon’ being such a huge hit, they tried to market ‘Way of the Dragon’ as a sequel to ‘Enter the Dragon’. So, they renamed it to ‘Return of the Dragon’. And then we have Game of Death 2 aka Tower of Death. I don’t even know which one is the correct name. It’s also possible that these are two slightly different cuts of the same film.
