King Henry II has his sons -- Richard, Geoffrey, and John -- locked in a cellar. They believe they are to be executed. They hear a door open and someone enter the cellar:
RICHARD: He is here. [beat] He'll get no satisfaction out of me. He isn't going to see me beg.
GEOFFREY: Why you chivalric fool, as if the way one fell down mattered.
RICHARD: When the fall is all there is, it matters.
Fine, fine movie, with some of the richest dialogue I've ever heard, and an amazing cast (featuring early turns by Anthony Hopkins, Nigel Terry, and Timothy Dalton).
