Hi, Stephen. Your upload seems to be unavailable now. Copyright strikes, I presume? Well, I am no law student; but based on what I understand, you can dispute the strikes. The film is more than sixty years old and belongs to the public domain now. I think that is what the Copyright Act, 1957 implies. Good luck.

A copyright strike indeed - from some company calling themselves "Tamada Media". I'll look into the copyright law and see if I can dispute. Thanks

Update: I tried disputing, but the company refused to give up their claim. I can appeal their decision, but it seems the process is the same and it's still them that decides, not YouTube. If my appeal fails, my account risks getting closed, so I won't bother since I don't see why they'd accept my appeal if they denied my original dispute. It seems any company can make any bogus copyright claim and YouTube just accepts it, regardless of what the evidence is.
