I am not an action aficionado. I can enjoy a good action movie if I'm in the mood for it, but it's not a genre I actively seek out. As a result, this list is probably both naive and biased.
Also, since there are a boatload of movies which have action in them but are not primarily action movies, my criterion for inclusion was that the film have one or more of what I would consider Action Movie Heroes.
