This is Smyth's directorial debut; a local production regular, she's coaxed freakishness by the fistful from her cast and they've rewarded her, and their audience, with bucketloads of comic horror.
Principal players are two families: the middle-class Jewish Bienekes, bewildered to find themselves enmeshed in an Addams-dominated world spinning on its macabre axis.
The versatile Alasdair Hay as Addams' patriarch, Gomez, is the perfect foil for on-stage wife Morticia (Augusta Smith), who is scarily natural in the role.
Playing the Bieneke seniors, Alice and Mal (Nanu Turner-Sarah and Mark Reid) are exactly as original writer, cartoonist Charles Addams (yes, another Addams) intended.
John McNaughton, the moon-loving Fester, is another made for his part. Equally convincing is Susan Wenborn, the incontinent, befuddled grandma.
There's predictable mayhem when the Bieneke's son Lucas (Anthony Estrada) falls for the crossbow-touting Wednesday Addams (Brogan Hastie).
Of all the weirdos this show produces, the star performer prize goes to Steve Holmes; his guttural growls as towering zombie butler, Lurch, beggar belief.
So much talent in one small space is confirmation musical theatre remains one of this city's true entertainment gems.
