Amazon MGM Studios is in final negotiations to acquire Megan Park’s sophomore feature “My Old Ass,” starring Aubrey Plaza and Maisy Stella, following its Sundance Film Festival debut.

The high-concept film — which was produced by LuckyChap’s Margot Robbie, Tom Ackerley and Josey McNamara, with Indian Paintbrush’s Steven Rales — made its world premiere on Saturday night in a sold-out screening at the Eccles Theatre in Park City, UT. The deal is for roughly $15 million. It is one of a handful of high-profile Sundance movies that are fielding offers from several bidders, including “Super/Man: The Christopher Reeve Story” and “Will & Harper,” a road trip documentary with Will Ferrell and his best friend, Harper Steele.

Amazon MGM is targeting a wide theatrical release for the film in the U.S. and Canada, with international territories still to be determined. Like all of its titles, the ultimate home will be Prime Video. “My Old Ass” landing at Amazon MGM comes after LuckyChap’s successful collaboration with the studio on Emerald Fennell’s “Saltburn,” a sexually charged look at the British class system. The critically acclaimed film, which grossed $20 million at the box office, blossomed into a bonafide pop culture phenomenon when it was released on Prime Video.

Described as a “sweet teenage love story, a lively contemporary comedy and a riff on time-travel films all in one,” “My Old Ass” follows the bright-yet-irreverent Elliott (Stella, in her feature film debut), who the summer before college, comes face-to-face with her older self (Plaza) during a mushroom trip. Elliott finds herself questioning her life choices and the relationships around her, while she prepares to leave her childhood home. Percy Hynes White, Maddie Ziegler and Kerrice Brooks also star in the coming of age comedy.
