Oh. What. Fun.

Claire Clauster is the glue that holds her chaotic, lovable family together at the holidays. But this year, after planning a special outing for them, they make a crucial mistake and leave her home alone. Fed up and feeling under appreciated, she sets off on an impromptu adventure of her own. As her family scrambles to find her, Claire discovers the unexpected magic of a Christmas gone off-script.

Directed by Michael Showalter, Oh. What. Fun. leans on a strong ensemble — Michelle Pfeiffer, Denis Leary, Felicity Jones — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about comedy titles of 2025.
