Bigelow and screenwriter Mark Boal chatted with the network news show about the film, in a pretty nice segment that includes a healthy amount of new scenes from the film and behind-the-scenes footage. "Nightline" broaches the accusations that have been leveled against the filmmakers that they were working with classified material, and it's something they outright deny. "I certainly did a lot of homework, but I never asked for classified material. To my knowledge I never received any," Boal said. And indeed he chalks up the realism in the film down to doing the kind of work he did as a journalist.
"I picked up the phone and started calling sources and asking them what they knew and taking referrals and knocking on doors and really approached it as comprehensively as I could," Boal said about what he did when he learned Osama Bin Laden was dead, something that greatly reshaped the film he and Bigelow were already planning about the hunt for the terrorist leader. "It was all based on first hands accounts so it really felt very vivid and very vital and very, very immediate and visceral of course, which is very exciting as a film maker," Bigelow said.
