GCHQ Challenge (December 2004): solution

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

For the 1991 film, The Silence of the Lambs, repeated letters are removed from the film title, giving:

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:

Plain: ABCDEFGHIJKLMNOPQRSTUVWXYZ
Cipher: RUVWXYZTHESILNCOFAMBDGJKPQ
ANTHONY HOPKINS   JODIE FOSTER

The complete solution is shown below, with the films in chronological order. And the hidden quotation? Reading diagonally down from the top left corner, we find "Here's looking at you, kid", just one of Humphrey Bogart's memorable lines from Casablanca.

And if you managed all that? Congratulations. Here's looking at you!
