Cumming shows range in one-man 'Macbeth'
At first he looks so tiny, the man curled up on the hard narrow cot in the vast sick-green emptiness of an old insane asylum. If not for the closed-circuit TVs and code-lock on the door, the place could still be Victorian. And if not for the unexpected, magnificently fierce discipline of Alan Cumming, the play -- a 100-minute solo reimagining of "Macbeth" in a mental hospital -- could easily have been a gimmick.
