Medea has nothing on Regina Giddens. The matriarch at the head of Lillian Hellman's Southern Gothic melodrama The Little Foxes is one of the most treacherous villains ever to walk across a stage. And with her slithering brothers Benjamin and Oscar Hubbard, she completes a gruesome troika. The cast of Main Street's wicked spring production lived up to the deliciously nasty script. As Regina, Claire Hart-Palumbo did everything but spit venom into her victims' eyes. Robert Leeds made a heartless, machiavellian Benjamin, clearly willing to cut off his siblings at the knees. And Thomas Baird, as Oscar, a man who alternately beat his poor wife and cowered before his mighty family, was shamelessly spineless.
