Hmmm, I've known for a long time that I have a problem recognizing faces. I read about being 'face blind' a few years ago and learned it's an identified trait. I took the test linked above and got 60%.
I'm pretty good about hearing differences in voices, so it's not too much of a problem. Or I can sometimes recognize their walk or mannerisms. That leads to staring at people as they approach, and sometimes they're just walking by so they give me a sideways glance.
It's a pain to watch a movie unless there are few actors and are very different. I don't bother learning actors names because I won't recognize them in other films.
