Well, if you want to appeal to the general populace, how about: Time Tunnel (SF series) Colditz Hogan's Heroes (series) Subway (French film with Christopher Lambert) Beauty and the Beast (series) The Fugitive (new movie version has a scene in the tunnels of a dam) The Borrowers (BBC) Ladyhawke And lots of movies about mining, but darned if I can remember any titles at the end of a long week.
