I don't think I can give you a legal answer, but I certainly have an opinion, which is: Duda is out of line.
Evidently Kelly's video doesn't even mention Mike Galster, and that is bizarre. Mike did more than anyone to break the whole tainted blood story. It was Mike who came across the infected plasma donors while he worked in Cummins Prison Farm. It was Mike who put two and two together when the Mounties traced the contaminated blood to Arkansas. It was Mike who accepted the risk of being the whistleblower by writing his fictionalized version of the true story. It was Mike who gave the interviews and who did the whole press conference at the National Press Club in D.C. with the press from both Canada and the U.S. in attendance.
And, of course, it was Mike who hired Kelly to do a documentary video. In my hearing, it was always Mike's story, not Kelly's. Kelly of course had a big role in the filming and research. But even there, it wasn't exclusively his own film work. Others contributed and edited and researched. To my mind, there is no question that this was Mike's project, paid for by Mike, and that the finished video did NOT belong to Kelly Duda.
Kelly obviously doesn't see it that way and at some point, long before the video editing was finished, he broke off relations with Galster and others associated with the whole venture. I think he yearns to be a film director and he sees this video as his entry. He used to talk freely about his ambitions in that direction.
Such is my opinion, anyway. Naturally, if others have information or views about this, I'll be interested to hear them.
Duda is trying to take credit for something he was only hired to do. If it wasn't for Mike, there would be no film!
