Chloë Grace Moretz, Dominic Sessa Join Amazon MGM Holiday Comedy ‘Oh. What. Fun.’ (Exclusive)

Chloë Grace Moretz and Dominic Sessa are joining Michelle Pfeiffer for a little Christmas cheer.

The two actors will star alongside the screen icon in Oh. What. Fun., an Amazon MGM holiday comedy that hails from director Michael Showalter, who is behind the studio’s upcoming Anne Hathaway romantic drama The Idea of You.

Described as both a love letter to moms and tonally a cross between Home for the Holidays and Planes, Trains and Automobiles, the story centers on a woman named Claire Clauster (Pfeiffer) who organizes a special Christmas outing, but her family forgets her in the shuffle. By the time they realize their mistake, she’s gone missing and their Christmas is in jeopardy. Luckily, nothing will stop Claire from giving her family the holiday they deserve.

The studio did not comment on the roles, but sources say the duo will play two of the woman’s grown children.

The script is based on a short story, published by Amazon Original Stories, written by Chandler Baker. Showalter and Baker wrote the script for the feature.

Showalter is producing the film via Semi-Formal Productions alongside Jordana Mollick, Tribeca’s Berry Welsh and Jane Rosenthal, and Kate Churchill.

The team is planning a late-May production start in Atlanta.

Moretz recently starred in Amazon’s sci-fi thriller series The Peripheral as well as the sci-fi thriller Mother/Android directed by Mattson Tomlin. She is repped by CAA and Sloane Offer.

Sessa is coming off of his feature film debut in Alexander Payne’s coming-of-age film The Holdovers, opposite Paul Giamatti and Da’Vine Joy Randolph. For his performance in the film, Sessa was nominated for a BAFTA Award for best supporting actor and won best breakthrough performance at the 2024 Critics Choice Awards and Film Independent Spirit Awards. Since his breakout, he has also booked a role opposite Rose Byrne in the true-life indie feature Tow. He is repped by CAA, Untitled Entertainment and Hansen Jacobson.
