The ambitious Porchlight Music Theatre took a step in its evolution last season when it signed an Equity development contract, enabling them to hire one Equity performer per show, with a goal of expanding the number of Equity performers over the years. After seeing their current production of The Secret Garden, one might wonder if it was necessary to sign that contract at all. Of course, without it they wouldn't have been able to hire Michael Aaron Lindner, who won a Jeff Award last year as their Sweeney Todd and is a knockout as their Archibald here. The entire cast, though, delivers performances of such power and professionalism that you'd never know who was and who was not Equity without the little asterisk next to Lindner's name in the program. Director Walter Stearns and Music Director Eugene Dizon have assembled possibly the best all-around cast in the company's history.
