Just trying to understand here - How do we know he didn't have permission to use the clip?
Also, I watched the movie but it has been quite a while. Can anyone refresh my memory as to what exact point he was making with the clip in question? I just can't remember anything about that movie clip supporting any of his arguments.
I did watch the full clip of the ABC story. What is omitted in the article is that the visual effects supervisor, Karen Goulekas, says she is "very happy he used it(the clip in question)." If she's happy about it, that might indicate that they are not in danger of getting sued. Her happiness, and her willingness to discuss it, may also indicate that they are not trying to hide the source of the clip.
