If the movie trailer is a form of art -- or at least a genuine medium -- both the action and the indie movie trailer is genres. And, as with any genre, ripe for parody:
Sometimes you just need to sit back and watch some fan-made comic book film trailers. Like Grayson, for instance. It's the story of Dick Grayson's re-donning of the Robin mantle after the death of Batman. The trailer is surprisingly well made, especially the acrobatics.
...and then there's Italian Spider Man. There is nothing I can say about this that won't ruin everything.
Apparently it has been made into a web series. So, uh, if you have greater inclination to watch it than I do, let me know what you think of it.
