GCHQ Challenge (December 2004): help

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
RNBTCNP TCOSHNM   ECWHX YCMBXA

What's next?

Now all you have to do is work out the other 19 pairs, and find the hidden quotation!
