As Eve (Carrie Fisher) is walking Carol through the bookstore in one of her past memories, a "Star Wars" book is in plain sight. This is, of course, a reference to the movie that made Carrie Fisher famous as she played Princess Leia in the first "Star Wars" trilogy.
Susan Hogan was in two other versions of "A Christmas Carol": "An American Christmas Carol" (1979) and "Ebbie" (1995).
