I'm not totally face blind, but I'm definitely impaired. I recognize people I see regularly just fine if they are in a familiar context. In other situations, rely more heavily on voice, gait, and haircut. The idea of choosing movies based on "favorite actor" makes no sense to me.
On tests such as these, I'm happy when I get the "do you understand the instructions" training questions right. Sometimes I can pick a face that I've just seen out of a short lineup based on verbal description of a single feature ("bushy eyebrows" or "full lips"), but usually I'm just purely guessing, hoping that my subconscious has the fabled "blind sight" that I can't consciously access.
