"As the shellshocked Milne newly returned from the Western Front,
Mr. Gleeson wears a virtually unvarying expression of acute intestinal distress.
Unable to connect with the infant or continue to write his popular plays, Milne
drags the child and his ghastly wife (Margot Robbie) — “I had a baby to
cheer you up!,” she whines — to the paradisiacal forest in Sussex where
the books will take shape."
