I have to assume Google is involved somehow. I suppose different AI art programs have different methods.

People have taken to posting images on social media of AI-generated posters for movies. And the text is often similar, but not the same. For example, "The Handmaid's Tale" from Dall-e came out "The Mandal" or "The Thandal."  "The Two Towers" came out "Trill Rows."

The images were a decent match. Women in hoods, or veils for the former, two medieval towers for the later.

These AI programs are pretty tied into pop culture. They will produce celebrities, fictional characters, etc., pretty accurately. In a toon or hand-drawn looking style if you want. Putting in "Star Trek" can generate reasonable likenesses of Kirk and Spock.
