I see a lot of "mickey mouse" but if this is Disney IP, then it includes Star Wars and Marvel, no?

You can literally make your own Marvel movie now! Legally!

If you read the release, it explicitly does not include the likenesses of human actors. Only animated and illustrated characters are included. (Although, that does cover animated/illustrated versions of characters that are typically portrayed by human actors...)

This is almost certainly due to the photographic/human likenesses of actors being under an entirely separate license and royalty contract than pure IP from Disney.
