Performer/film credits for clips in Christian Marclay's "The Clock"

I was surprised to learn that Christian Marclay's "The Clock" actually has an IMDb listing. I was also slightly disappointed/surprised to see that the films and performer credits were fairly sparse. I went to see this film at MoMA and reveled in ferreting out every clip/film that I could recognize and wondered if there's any value in trying to add more information to this listing. The closest comparison that I could find was for "That's Entertainment", which is similar in that it's a film filled with recycled clips from other films. The listing for "That's Entertainment" looks like this: The additions for "The Clock" would probably resemble the section under "Rest of cast". This may be a fool's errand to start since "That's Entertainment" is roughly two hours in length with maybe a hundred clips whereas "The Clock" is literally 24-hrs and contains roughly 12,000 clips (though many cannot be and do not require any attribution) but it's an interesting idea. Just wanted to get some input from other perspectives. Thanks.
