Creative incest. Should Peter Jackson have directed Harry Potter films? Or should George Lucas have directed The Motion Picture back then?
Should James Cameron have directed TERMINATOR and
Should Irwin Kershner have directed THE EMPIRE STRIKES BACK and
NEVER SAY NEVER AGAIN?
Should Martin Campbell have directed GOLDENEYE and
THE MASK OF ZORRO?
Should James Whale have directed FRANKENSTEIN and
THE INVISIBLE MAN?
Are directors only allowed one franchise per career? Of course not, that would be silly.
(P.S. I would so
buy a ticket to see Nolan's take on IRON MAN.)
