Baby bill - what a cutie
Baby tommy
One of my kiddos has fairly mild prosopagnosia, and before we knew that about her, she frequently confused Bill Murray and Tom Hanks whenever one or the other was on screen. I thought she was pulling my leg!
Face blindness is nuts. It turns out that one major way people are differently recognizable to her is hair style / hairline. The other big one is glasses/no glasses. Apparently Tom Hanks and Bill Murray are similar in this way. Outside of that, someone needs an outlying defining feature like a pretty large nose.
