libyaStan Lee disapproves, but the proactive geeks of the doc film Superheroes are patrolling our cities in tights, capes and belts with “sonic grenades” and stunt guns. As in, “Yeah, I have been tased by my own stunt gun before.”

The film shows endearing defenders who head to “the roughest parts of their neighborhoods” to confront trouble and how not crazy they are. Better watch out, crime! They know parkour.

Follow the vigilantes from San Diego to New York — where they are “driven by darker impulses” — on August 8th when the documentary premieres on HBO.
