Eulogy

The "In Memoriam" section at the end of the credits for this episode lists 40 names, some sharing surnames with cast and crew members, suggesting the production invited personal submissions to honor lost loved ones. Included are Elena Giamatti, (Paul Giamatti's sister), Derek Brooker, (likely the father of creator Charlie Brooker, known to have died during post-production), Eileen Kinsella, (shares a surname with supervising producer Mark Kinsella), Jeff Sutton, (shares a surname with producer Louise Sutton), Andy Barrett, (shares a surname with director Christopher Barrett), and Lee Kirby, who shares a surname with music supervisor Mark Kirby. The list also includes Lance Reddick, the acclaimed actor who died in 2023, and Mark Found, a UK television sound professional. This memorial tribute fits the episode's themes of grief and remembrance, honoring real-world losses of the production team alongside a story centered on processing death and memory.

At 39.30, when Philly is reading the note that Carol left for him, the words she narrates are not entirely the same as what is in the note.
