Blurred arms effect?
This film features that iconic shot of Bruce Lee moving his arms in a sort of motion blur special effect. If you're not sure what I'm talking about, go to about 3:25 in the trailer https://www.youtube.com/watch?v=uWeT0ja7Icw
My question is this...
What that just a cool effect or is that supposed to be something in particular that a legendary Wushu master could do?
