It's A Wonderful Life entered the public domain and was taken back from us. The rights holder forgot to apply for an extension. After it lapsed they argued that done they held the rights to the story it was based on, the rights to derive from that story, the score, etc., they should have the film too.

I can not, with humor, get across how dumb that sounds to me. So I'll state it plainly. That's amazingly stupid. And it worked.
