On the original 2001 DVD there was a great speech by Author C. Clarke.
Unfortunately, the DVD was letterboxed, so I later replaced it with a widescreen DVD and then a 4k disk. None of them have the speech.
I really want to go back and hear it again. He spoke about being convinced there was intelligent life elsewhere, and wondering how similar or different they were to us.
I would think any clip of ACC saying something significant on camera that was ever distributed publicly would have been posted on YouTube or Archive.org.
