Written by David Koep, SPIDER-MAN opens nationally. The first in the Sam Raimi/Tobey Maguire superhero trilogy ushers in the age of Marvel with a $100 mil. weekend. An appropriately overproduced, effects-heavy corporate confection soundly de-energized by Willem Dafoe's bland, resolutely cartoonish Green Goblin villian. With Kirsten Dunst, James Franco and Cliff Robertson.
