EXCLUSIVE: Love Is Not the Answer, the feature directorial debut of Juno and Superbad star Michael Cera, has added Lucas Hedges (Sorry, Baby), Julia Best Warner (Ratched) and Shirley Henderson (Harry Potter) to its leading cast as production continues, Deadline has learned.

Character details are under wraps. As announced when the film was introduced for sales at the Cannes Market, the film’s leads are Pamela Anderson, Steve Coogan, and Jamie Dornan. Fred Hechinger was also announced as part of the cast in May, though he has since departed due to a scheduling conflict.

Produced by 2AM and Brookstreet Pictures, Love Is Not the Answer is billed as a precise yet unpredictable, absurdist comedy that moves between hilarity and heartbreak as it explores modern loneliness and the search for connection. Further details remain under wraps.

Miles Cameron, Joseph Longo, Hannah Heller, Alyssa Bresnahan, and Maryann Urbano round out the cast.

Cera also penned the script. Producers on the project include Julia Oh, David Hinojosa, Christine D’Souza Gelb, and Brookstreet Pictures’ Nick Gordon and Carter Stanton, alongside Cera, Peter Niehoff, and Jomon Thomas for Mirador Pictures. Brookstreet also counts Trevor Matthews among the exec producers, alongside Natalya Pavchinskaya of Mirador Pictures, Brandon Thomas Lee and Jake Cloobeck of Evania, Betsy Niehoff, and Brendan McHugh. IPR and TPC are providing additional finance. MK2 Films is handling international sales while D’Souza Gelb and CAA Media Finance co-rep domestic.

Oscar-nominated for his starring role in Manchester by the Sea, Hedges has most recently been seen in films including Sorry, Baby, Shirley, Let Them All Talk, and French Exit. He is repped by Untitled Entertainment and Brecheen Feldman Breimer.

Previously seen in Netflix’s Ratched, Warner is repped by Cinterra Entertainment.

A BAFTA nominee who played Moaning Myrtle in the Harry Potter films, Henderson has also been seen in multiple installments of the Bridget Jones franchise — including the most recent installment, Bridget Jones: Mad About the Boy — as well as Sofia Coppola’s Marie Antoinette, Bong Joon Ho’s Okja, Netflix’s Dept.
