He Wanted the Moon has found its scribe. Pulitzer Prize-winning writer Tony Kushner will adapt the memoir for Brad Pitt’s production company, Plan B, and Cross Creek Productions, Cross Creek’s director of development John Hilary Shepherd confirmed to EW.

The book is written by Mimi Baird and Eve Claxton and focuses on the life of Mimi’s father, Dr. Perry Baird. He was a Harvard graduate physician who researched the causes of depression, which he suffered from along with bipolar disorder. Baird was institutionalized many times, received a lobotomy, and died of the induced seizures.

Mimi Baird unearthed her father’s manuscripts, which offered a glimpse into his mind as he grappled with mental illness. The book is composed of the manuscript along with annotations written by Mimi Baird, adding insight from interviews with family members and Dr. Baird’s former colleagues.
