H44 is definitely sincere, and he's not making anything up. What you see is what you get.
And he's definitely made his movie. I watched it the other night, before he removed it from youtube (or made it a private listing). Since it's now private, I won't reveal even any minor details, but the version I saw seemed to be the locked edit, with rough audio.
And H44, the shot in question, that you started this thread for -- it doesn't matter. Just get that audio work done, and release the damn movie.
Dude, do you have any idea how many copyrights I violate in Antihero? None intentionally, but I didn't catch them until post, and by then I had figured out that I wouldn't be getting into Sundance anyway. Dude, the kind of festivals you'll have even an inkling of getting into won't care about, and probably won't notice a phone number. Nor is the company going to notice. Fuck it, just finish the damn movie and move on to the next project.
