The names are those of film actors and actresses.
Each actor is paired with an actress, according to a film they both starred in, and their names encrypted with a simple substitution cipher based on the name of the film as a keyword.
Example

THESILNCOFAMB
The missing letters are then added, giving:
THESILNCOFAMBDGJKPQRUVWXYZ
This is then rotated to give the ciphertext alphabet:
RUVWXYZTHESILNCOFAMBDGJKPQ
This is used as the ciphertext alphabet to encrypt Anthony Hopkins and Jodie Foster:
