Aubrey Plaza and Maisy Stella Go Tripping in ‘My Old Ass’ Trailer

Maisy Stella, playing 18-year-old Elliot Labrant, finds her future self at age 39 (played by Aubrey Plaza) in the trailer for Megan Park’s My Old Ass, which dropped on Thursday.

The time-bending coming-of-age tale comes by way of a summer mushroom trip that Elliot goes on with her girlfriends while holidaying in cottage country north of Toronto before heading off to college. While tripping next to a campfire, Elliot meets Plaza’s character seated on the same log, only she’s two decades her senior — and full of warnings about what her younger self should or shouldn’t do.

“You’re kind of hot for being middle-aged,” Elliot tells her older self at one point in the trailer, to which a defensive younger Elliot replies sternly, “I’m a very young adult.” Eventually, Elliott realizes her older self, or “old ass,” has her rethinking everything about family, love and a summer set to change her forever.

After her older self warns 18-year-old Elliot about falling in love, everything gets complicated when she meets Chad, the person her “old ass” specifically red flagged. Soon younger Elliott opens herself up to what her future self might have to show her about life and love.

My Old Ass also stars Percy Hynes White, Maddie Ziegler and Kerrice Brooks, and is produced by Tom Ackerley, Margot Robbie, Josey McNamara and Steven Rales. Park’s sophomore feature after The Fallout, which she also wrote, will get a limited run in theaters from Sept. 13, with a national rollout to follow.
