“My spirit age is a solid mid-30s, with a heavy shake of the elderly,” said Ms. Walter, who is 37. “Once in high school I walked into a class that was my class, and someone thought I was a substitute teacher. And I love soup. I am obsessed with soup.”
“I think mine is younger,” said the film’s director Katie Aselton, 43. “I don’t know if it’s because I have teenage daughters.”
“It was interesting making this movie, where I had one leg, truly, in with the younger generation,” Ms. Aselton said. “I feel these insecurities. I feel all of the pressures of society. And then I had one leg over with the older ladies being like, ‘Yeah, but if you just let it all go, and be free, release it, own yourself, be you.’”
Ms. Paige, 31, said her spirit age feels similarly split. “It’s like I’m either 7 or I’m 93,” she said. “I’m pretty basic and simple in what it is I want out of life, which I feel like is an older person, but I’m very much, like, alive and trying to take in all that I can and wanting to jump on my bed and do cartwheels.”
“Mack & Rita” costume designer Allyson Fanger, who also dressed Ms. Fonda and Lily Tomlin for their Netflix show “Grace & Frankie,” said many of the hallmark hats, turtlenecks, wide belts and full skirts Ms. Keaton wore in the movie were the actor’s own. But other items, including those unforgettable python boots, had to be acquired in multiples for both Ms. Lail and Ms. Keaton.
