Eleanor Elizabeth Bamber (born February 2, 1997) is an English actress best known for her roles in the BBC series Les Misérables (2018), The Trial of Christine Keeler (2019–2020), and The Serpent (2021), and the Disney+ series Willow (2022).
Book plot: Finn and Hannah have spent everything Christmas together since they were college sophmores. They've built found family traditions throughout their twenties...but this is the year that may all change.
I picture this as a dozen 30-45 min episodes, going year by year, so the set up is less like the book's chronology and more like the Netflix remake of The Four Seasons.
