Somewhere in playwright Theresa Rebeck's past there must have been a 420-too-friendly techie who smoked up the booth, a big-name hack who got the plum job and a lover who walked out without a word. Or maybe these professional disasters and personal heartbreaks, captured so hilariously and affectingly in the Cincinnati native's 'The Understudy,' are simply the products of Rebeck's rich imagination. Either way, the comedy has a ring of authenticity that anyone who's ever acted (onstage or in life) should appreciate.
