I used to think stunt people was something Star Trek left behind after the original seriesWhy would you think that? Stunt doubles are used all the time for action scenes, it's hardly an abandoned practice?!
I just meant that, until recently, in my eyes TNG always did such a great job of concealing stunt people. In the original "Star Trek", on the other hand, I thought stunt people were obvious from the very first action sequence I ever saw on it!
