Umma[Note 1] (Korean: 엄마, eomma) is a 2022 American supernatural horror film written and directed by Iris K. Shim.

The film stars Sandra Oh, Fivel Stewart, MeeWha Alana Lee, Tom Yi, Odeya Rush, and Dermot Mulroney.

When Amanda receives the cremated ashes of her recently deceased estranged mother, or Umma, in a suitcase from her uncle Mr. Kang visiting her from Korea, she is confronted with memories of her abusive childhood.

The film ends with Amanda rediscovering her family heritage and sharing it with her daughter, as well as coming to terms with Chrissy's need to live her own life.

[11] In the United States and Canada, Umma was released alongside Jujutsu Kaisen 0, The Outfit, and X, and was projected to gross $500,000–1.5 million from 805 theaters in its opening weekend.

The website's consensus reads: "Despite Sandra Oh's typically strong performance and glimmers of potential from writer-director Iris K. Shim, Umma is a cliché-ridden missed opportunity.

Andrew Baker from Variety wrote: "Oh aces her leading role with customary aplomb, and Stewart makes for a game scene partner, but Shim’s economical-to-a-fault screenplay rarely allows them enough downtime to fully flesh out their characters."

Frank Scheck at The Hollywood Reporter noted Oh's committed performance but found the film to be a mediocre B-movie, writing: "Writer-director Shin's labored attempts to use genre tropes to explore the complexities of domineering mother-daughter relationships never fully develops.

Kate Erbland from IndieWire also gave a mixed review and wrote: "Despite its flaws, Umma is an impressive debut for Shim, the kind of outing that hints at plenty more under the hood or tucked inside a massive suitcase, just bursting with secrets."

In a positive review, Tracy Brown from Los Angeles Times wrote: "Think more classic Gothic horror than ghastly over-the-top occult.
