Jackie Chan, the HK actor, filmmaker, martial artist, and stuntman, ended films with a blooper real. It showed stunts being practiced, and failing, with injuries. A reality check, a "what you've seen today was staged", a "don't think this was real, and then make poor life choices". I liked the integrity of that.<p>Lots of people only see BD's demo videos, and not their making-of videos. Or don't have the expertise to interpret those. So each time BD does another demo video, I think of Chan's films, and wonder if BD might do better.
