No You Didn't Try To Cast Damon As the Sub-Mariener. Just say "no". Quit putting the new super-stars in super-hero movies. Quit putting square pegs in round holes. Didn't you learn your lesson with Daredevil? Anyway, the Sub-Mariner, he looks GREEK for lords sake! Damon looks Irish. Let's keep the casting realistic shall we. The Sub-Mariner came from ATLANTIS, which has Greek roots as I recall. I never really read the comic, but c'mon, if it offends me, how will it work on those who actually liked the strip? Say it with me now: Stop making comic book movies if you didn't actually read the comic book.
