Answer
In King Lear, Dennehy portrays the title character, a ruler who divides his kingdom among his three daughters based on their flattering words rather than their true love for him. As the play progresses, Lear's poor judgment leads to his downfall and a tragic end. Dennehy's powerful performance captures the complexity of Lear's character, from his initial arrogance and rash decisions to his eventual descent into madness and despair.
