Andy Garcia, Walton Goggins, and Molly Parker are the latest to join LD Entertainment’s Words On Bathroom Walls, from director Thor Freudenthal. Based on Julia Walton’s debut novel, the story follows the character of Adam (played by Charlie Plummer) as he tries to navigate high school life while living with paranoid schizophrenia and battling wild hallucinations. Luckily, an experimental drug trial promises to help hide his illness from his peers and most importantly from Maya, the girl of his dreams.

Garcia is playing Father Patrick, the kind and unexpectedly witty priest at the private high school Adam attends. Parker will portray Adam’s devoted single mother who persistently studies everything to do with schizophrenia and believes that someday there will be a medication that will help her child. Goggins is playing Beth’s partner Paul, a decent and caring man who wants what is best for his stepson but realizes that Adam has little interest in becoming his friend.

Previously announced cast also includes Taylor Russell and AnnaSophia Robb.

Nick Naveda wrote the screenplay, which LD Entertainment’s Mickey Liddell and Pete Shilaimon will produce.

Garcia, who has two movies out this year with Book Club and Mamma Mia! Here We Go Again, is repped by CAA and Brillstein Entertainment Partners.

Repped by CAA, Circle of Confusion and Red Management (Canada), Parker is known for her roles in Lost in Space, Deadwood, and House of Cards.

Goggins, recently seen in Tomb Raider and up next, appears in Disney/Marvel’s Ant-Man and the Wasp, is a client of Darris Hatch Management and ICM.
