The cast of My Old Ass features some major movie stars and a few up-and-coming actors, and they all worked together to tell a great coming-of-age story. My Old Ass tells the story of Elliott (Maisy Stella), a girl who is about to go to college who gets some unexpected advice from an unexpected source: an older version of herself, played by Aubrey Plaza. With a Rotten Tomatoes score of 90%, My Old Ass is a better performance from Plaza than Megalopolis, the recent Francis Ford Coppola film. A large part of that quality is due to the stellar performances and chemistry of the film’s small cast.
