Script for the film War of the Worlds, 1955, one of my favorites.

http://leonscripts.tripod.com/scripts/WARWORLDS.htm

It has some great lines, like;

GENERAL MANN This is the only place we’ve had time
to surround them with sufficient force
to contain them. What happens here
will be a guide to all other operations.

Or, a few minutes later, after action begins:

GENERAL MANN
(Fast, looking out)
What’s that skeleton beam they’re
using?

CLAYTON
It must neutralize mesons somehow.
They’re the atomic glue that holds
matter together.
(Grimly)
Cut across their lines of magnetic
force and any object will simply
cease to exist.

(There are a few differences between the script and the soundtrack. Here is one I remember vividly:

CLAYTON Take it from me, General, this type of defense is useless against that kind of power.
