BEDEVERE: Stand by for attack!!
[CUT TO enormous army forming up. Trebuchets, rows of PIKEMEN, siege
towers, pennants flying, shouts of "Stand by for attack!" Traditional
army build-up shots. The shouts echo across the ranks of the army.
We see various groups reacting, and stirring themselves in readiness.]
ARTHUR: Who are they?
BEDEVERE: Oh, just some friends!
