As for using his image, without a release I would not. He has no reason to think he will end up in a commercially released video. Even in public, if you use someone's likeness for commercial purposes you still need a signed release, unless you have posted signs everywhere letting people know that walking/rolling into a particular area means that they are consenting to use their likeness. As a general principle, blur out the faces of people you do not have releases on.
