Yes, I believe it does. Since I did not give it any explicit descriptions about how harry potter (or all the other characters) look. For example Hermione nearly resembles Emma Watson in the anime image generated, even though I did not specify it as such. It does seem to recognize popular characters/actors/artists directly from probably millions of available images. I have tried with popular actors as well, and it works pretty well - eg. with a prompt: Tom Cruise as an Indian god Vishnu. It works surprisingly well. I have tried DALL-E (but I exhausted my free images pretty quickly) and the results were different from Midjourney.
