What date did writer Michael Chabon sign on to write the film 's script ?
While " The Amazing Adventures of Kavalier and Clay " was , like " The Mysteries of Pittsburgh " and " Wonder Boys " , an essentially realistic , contemporary novel ( whose plot happened to revolve around comic - book superheroes ) , Chabon 's subsequent works — such as " The Final Solution " , his dabbling with comic - book writing , and the " swashbuckling adventure " of " Gentlemen of the Road " — have been almost exclusively devoted to mixing aspects of genre and literary fiction .
