“We continued to rewrite it all through the next five months, on set, nonstop. And it was a blast,” Marcum recalled. “A blast” wasn’t how everyone viewed it—while Downey thrived and Paltrow soon adapted, Bridges remained uncomfortable. “Jeff loved to have a script a good three months before he did the scene,” Favreau recalled. That wasn’t remotely possible on Iron Man. “Robert would come in and bounce the script off the wall of the trailer every day.”
