The new comedy My Old Ass stars Maisy Stella and Aubrey Plaza as younger and older versions of a queer character who thought she had her sexuality all figured out, that is until she meets Chad.

Megan Park’s “My Old Ass” isn’t the first film to ask whether it would be better to have a warning about what life has in store. But the borderline-sci-fi film set in an Ontario lake town, which stars Maisy Stella and Aubrey Plaza alongside a multigenerational cast of veteran and first-time actors,

Megan Park’s “My Old Ass” is premised on a familiar conversation starter: if you could tell your younger self anything, what would it be? Writer/director Park dreams up a supernatural scenario in which this actually comes true for protagonist Elliott, played at age 18 by Maisy Stella (in her film debut) and at age 39 by Aubrey Plaza.

Maisy Stella hadn’t heard the word “action” in years. The 20-year-old actor grew up on the set of the ABC drama “Nashville,” in which she and her older sister, Lennon, played the daughters of Connie Britton’s country music superstar.

Maisy Stella was 8 when she was cast in “Nashville,” a role that went on for six years. Now 20, she stars opposite Aubrey Plaza in the feel-good coming-of-age drama “My Old Ass.”

Maisy Stella plays a teenage girl on a mushroom trip who meets her 39-year-old self (Aubrey Plaza) in the coming-of-age movie "My Old Ass."
