A current tunnel that is used for escape is the one in The Saint.  A tunnel
that resembles the one you are studying in Georgia is the tunnel in Nava's
El Norte--quite unforgettable.
There are psychological tunnels.  The underground tunnel in Invaders from
Mars (1953) is a standout.  There are tunnels that take us to new worlds:
sometimes the world is a fantasy (Journey to the Center of the Earth, for
example).  Sometimes the world is a mythological place (as in Peter Weir's
Last Wave).
I found the use of the tunnel particularly innovative in La Nuit de
Varrennes, where at the end of the film we suddenly emerge from underground
in modern Paris.
Two films that contrast life underground with life on the surface are the
50s 'sociological' rescue films Ace in the Hole and The Well.  In both
films, the attempt is to dig a tunnel, and the attempts--well, they reveal
much about crowd psychology and what is required to go underground.
Needless to say, this is an interesting topic.
