I fear social cluelessness

Because I occasionally suffer it.

Worse, other people around me occasionally suffer as a result of its lodging in my brain.

Thankfully, it didn't happen yesterday (so far as I could tell)...

Comic Book Movie Maps: A Pointed Query

These search terms have come up empty for me:

• Matt Hatton
• Beth Garswood
• graphic design
• Superman Returns

I know those two names are connected with that discipline and that movie through The Art of Superman Returns by Daniel Wallace. They are credited with the post-New Krypton map of Earth "if Lex Luthor gets his way" in that book. I'd like to find out if they were responsible for other maps commissioned for use on-screen in that same film.

Are they still working in the field?
