I just saw this play produced at the Oregon Shakespeare Festival. There are only so many family skeletons you can expose, and "Humble Boy" borrows liberally from that well-stocked closet. But those it drags out are embodied in well-defined characters and presented with fresh wit, excellent pacing, gentleness, and poignancy. Felix's search for the physicist's "theory of everything" is handled lightly, never bogs down in technical jargon, and never overshadows the characters' concerns of the heart. Although I would have preferred a slightly different ending, it worked because the characters were true to themselves. A wonderful play.
