Matt Damon believes missing a role in 'Primal Fear' motivated him and Ben Affleck. This disappointment fueled their writing of the Oscar-winning screenplay 'Good Will Hunting'. Edward Norton's phenomenal performance in 'Primal Fear' was a key inspiration for the duo. They recognized the rarity of such substantial roles for unknown actors. This realization led them to write 'Good Will Hunting' with greater urgency and focus.
