I'm pretty sure he met George Lucas too. There's a picture of him looking at a miniature set for Return of the Jedi.
I know that Stanley Kubrick wanted Tezuka to be the art director on 2001: A Space Odyssey, but he couldn't do it. It would not surprise me at all if they did end up meeting eachother face to face before or after that.
