Charles Lenox Remond

Just now I went to amazon and read the freebie pages in How the Irish Became Black since I've never actually read the book yet, but should. In it there's a lot of stuff in the 1800's which I had no idea about, much less this figure O'Donnell in Ireland, etc etc. Anyway there was a reference to this guy Charles Lenox Remond who was a black guy (as though this was fortuitious and not often happenish) so I looked him up. Not a lot of web resources on the guy. Apparently a great orator (so he'd have to be played by Denzel?) who went with the delegation from the States over to a World's Anti-Slavery Convention in London.

No mainstream movies address this convention to my knowledge. If a movie like 300 can get made, easily a movie could be made about this guy, or the convention, and both. I'm sure Remond has made appearances in Civil War movies and he should, but I wonder how prominently and how detailed. I do believe it's one life not much explored. Here's a link to a blurb about him.
