Jake Gyllenhaal and 'The Affair's' Golden Globe winner Ruth Wilson ace their Broadway debuts in 'Constellations,' a compact play with big ideas about life, love and death that is, happily, as brainy as it is sweet-hearted...It's like being in an echo chamber filled with fun-house mirrors and can be a bit off-putting -- at least until the structural framework makes itself evident. Payne makes sure that it does, and that everyone's on the same page...director Michael Longhurst's staging touches both the head and the heart deeply. Even Tom Scutt's lovely set, a bare stage below and beside a huge collection of inflated white balloons, packs a poetic touch. And the cast is swoon-worthy. Gyllenhaal is laid-back and ever-genunine as the passive Roland. Wilson, a two-time Olivier Award winner, is sensual and irresistibly carefree -- a perfect foil. Together, they have something elusive: combustible chemistry. Heavenly sparks ensue.
