EXCLUSIVE: Widow’s Bay star Kingston Rumi Southwick and Arthur Conti, of Mike Flanagan’s upcoming Carrie, have joined Ariana Greenblatt in Egg Baby, Amazon MGM’s new romantic comedy from director Natalia Anderson and XYZ Films.

Written by Sawyer Perry, Egg Baby follows a rebellious artist (Greenblatt) and a golden-boy quarterback (Southwick) who are forced to co-parent an egg for health class, only to find that raising “Yolk-o” might crack open something real between them.

Conti’s role hasn’t been disclosed. XYZ Films will produce with Allison Friedman (The Mortuary Collection, The Fix), in association with BuzzFeed Studios. The film is set to stream globally on Prime Video.

Southwick is a fast-rising actor who has recently broken out with roles in two buzz titles. The first is Widow’s Bay, the breakout horror comedy from Apple TV, which has him playing Matthew Rhys’ son and scored the most Emmy nominations of any freshman series this year. The second is Apple’s hit legal drama Presumed Innocent, where he plays the son of Jake Gyllenhaal and Ruth Negga. Also seen in Amazon’s thriller series 56 Days, Southwick is repped by Untitled Entertainment and attorney Erik Hyman of Paul Hastings.

Currently, Conti can be seen opposite Hannah Einbinder and Gillian Anderson in Teenage Sex and Death at Camp Miasma, the Mubi slasher from Jane Schoenbrun that nabbed the Queer Palm at this year’s Cannes Film Festival. Previously playing a key role in Tim Burton’s Beetlejuice Beetlejuice, Conti’s upcoming slate includes Ti West’s Ebenezer, in addition to Flanagan’s series adaptation of the Stephen King classic Carrie. He is repped by WME, The Artists Partnership, and Myman Greenspan.
