OK, this isn't really inspired by Ray, but it did remind me of him for two reasons.
One is the story "The Martian" - that's the one about the Martian who takes on the look and behaviour of the human being you are thinking of, and who finds himself shifting identities constantly when he gets trapped in a crowd.
The other is that a number of these faces have connections to Bradbury, from having worked with him or appeared in adaptations of his stories.
