In the film version, Sigmund Freud (Anthony Hopkins) and C.S. Lewis (Matthew Goode) contend with background stories before they can go back and forth with their theories. Director Matthew Brown fills his film with context – scenes of air raids in London, a subplot with J.R.R. Tolkien – and leans into a story about Freud’s relationship with his daughter Anna (Liv Lisa Fries), which only delays the inevitable.
