A lot of credit goes to Rob Brown, who plays the increasingly frenzied Mortimer. He's a rubber-faced comic actor with an inexhaustible supply of double takes. And he exhibits some genuine chemistry with Jennifer Gill, whose Elaine, Mortimer's girlfriend, is nicely played. Brown's performance is also well complemented by Marilyn Duryea and Vivian Meisner. With apt comic timing they play the gently murderous aunties, who never allow anything to shake their belief in their own propriety. Adding solidly to the lunatic fun is Peter Schuyler's Teddy, Mortimer's brother, who believes he is Theodore Roosevelt, frequently bellowing "Charge!" as he rushes upstairs.
Director Eric Chase keeps most of the show perking at the appropriate farcical pace. Things occasionally get a little flat, though, after Jonathan, Mortimer's long-missing and criminally insane brother, shows up. Jonathan has his face periodically redone by his plastic-surgeon accomplice, Dr. Einstein, who in a misguided burst of inspiration has made the latest redo the face of Boris Karloff. This causes Jonathan to bristle whenever the resemblance is mentioned. It takes pitch-perfect mounting to make this character work without the casting coup that marked the original production, when Boris Karloff played the role. Here Justin Plowman, looking ominous but no Karloff look-alike, gives the role a too-real sense of menace.
Still, this is hardly fatal for a show, which makes vintage Arsenic a very palatable poison.
