Well here's a funny thing. I just put in The Hunt for Red October.
Cathy is played by TNG's Beverly Crusher and she's using a British accent!!!
EDIT: I just finished watching Red October. Man, that is a great movie. Now that's how you do a Tom Clancy movie. Even though the movie isn't jammed packed with action, every scene is great. There's tension and drama and everything feels important and edge of your seat.
