John Guare (rhymes with "air"; born February 5, 1938) is an Irish American playwright. He is best known as the author of The House of Blue Leaves, Six Degrees of Separation, and Landscape of the Body. His style, which mixes comic invention with an acute sense of the failure of human relations and aspirations, is at once cruel and deeply compassionate. In his foreword to a collection of Guare's plays, film director Louis Malle writes:
Guare practices a humor that is synonymous with lucidity, exploding genre and clichés, taking us to the core of human suffering: the awareness of corruption in our own bodies, death circling in. We try to fight it all by creating various mythologies, and it is Guare's peculiar aptitude for exposing these grandiose lies of ours that makes his work so magical.
