My Old A** trailer: Aubrey Plaza’s younger self hallucinates during hilarious magic mushroom trip in Margot Robbie-produced comedy

The hilarious first trailer for My Old A** starring Maisy Stella and Aubrey Plaza debuted Thursday.

In this coming-of-age dramedy, rising star Maisy stars as 18-year-old Elliott, who is spending her last summer on her family’s cranberry farm before heading off to university in Toronto.

After an accident with a mushroom, Elliott meets her future self (Plaza), who warns her not to fall in love with a guest worker on her father’s farm, played by Wednesday alumnus Percy Hynes White.

“I think it’s kind of clever because I’m middle-aged,” the younger Elliott tells the older Elliott, to which the latter quips, “I’m a young adult.”

Written and directed by Megan Park, My Old A** also stars Maddie Ziegler and Kerrice Brooks and is produced by Margot Robbie.
