While Garner and estranged husband Ben Afflecksplit after 10 years of marriagein 2015 amid cheating allegations, the actress maintains that the film is not a case of life imitating art.
“You actually, believe it or not, don’t use your own life as much as you might think,” Garner toldEntertainment Tonightat the film’s premiere. “It really is its separate, own, bear to get through. You just get into the place because that’s your job, and then you shake it off because you have to go home and raise your kids.”
