The story of Tony Revolori, who loved Saoirse Ronan and grew up to be F. Murray Abraham, told his tale to Jude Law, who grew up to be Tom Wilkinson, whose book inspired many. Zero worked with Ralph Fiennes, who slept with Tilda Swinton, who was murdered by Willem Dafoe at the behest of Adrien Brody, who framed Fiennes by threatening Mathieu Amalric and later murdering Lea Seydoux and Jeff Goldblum (and his cat). Fiennes escapes prison with help from Harvey Keitel, runs into cop Edward Norton and military concierge Owen Wilson, clears his name but sacrifices himself to nazi authorities to save Revolori and Ronan. Jason Schwartzman is a Jude Law-era lobby boy, and Bill Murray, Bob Balaban and some others are shoehorned in.

Stefan Zweig (Letter From an Unknown Woman) gets an “inspired by” credit. Cowritten with the guy who drew the paintings at Eli Cash’s house in Royal Tenenbaums.
Katy liked it alright. My mom did not.
