I remember the Hitchhiker's Guide casting kerfuffle about Mos Def. Ford has always been black in my brain, and had actually looked quite a bit like how he ended up in the movie. So when the wank started up, I was really confused and had to read the book again to realize that I had made it up in my brain. I was just sure he was described as a dark-skinned lanky dude with short dark hair and a friendly smile.

Only, not really. Apparently I had a mental link with the movie's casting agent, though.
