The double Oscar nominee says the same thing drew her to both “Marriage Story” and “Jojo Rabbit”: desire to work with each film’s writer-director, Noah Baumbach and Taika Waititi, respectively. With Baumbach, she developed the stamina required to work intensely — likening it to training for a marathon — and that prepared her to jump right into Waititi’s film. Up next: “Black Widow,” originally poised for an April launch and now rescheduled for November. While Johanssonn hopes to try her hand at directing one day, right now she’s focused on her production company, These Pictures. “I love producing and working with other artists and writers and actors and directors to fully realize their vision.”
