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 on Thursday. 

The coming-of-age dramedy features rising star Maisy as 18-year-old Elliott, who is spending her last summer on her family's cranberry farm before heading off to college in Toronto. 

Following a magic mushroom-induced mishap, Elliott encounters her future self (Plaza), who cautions her against falling for a visiting worker on her father's farm, portrayed by Wednesday alum Percy Hynes White. 

'Im kind of hot for being 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

My Old A** is Park's second film, following The Fallout, a 2021 drama about a fictional school shooting that stars Jenna Ortega.

Park is perhaps most recognized for her role as Grace Bowman on The Secret Life of the American Teenager.

The trailer shows Elliott preparing to leave for college and determined to make her last summer at home unforgettable. 

To celebrate her 18th birthday, she and her best friends head to a remote island for a mushroom trip. 

She and her closest friends set out to a secluded island to try magic mushrooms. 

Initially, Elliott feels no effect from the mushrooms, but then she finds herself face-to-face with a woman who insists she is Elliott's future self, played by Aubrey Plaza.

This future version of Elliott gives her a stern warning: stay away from anyone named Chad. Elliott thinks this will be simple enough. 

However, when she encounters Chad (Percy Hynes White), the very person she's supposed to avoid, her plans become complicated. 

As she spends more time with Chad, Elliott starts to reconsider the advice from her older self.
