Nathan Johnson and Victor Angelo and The Melville BoysThe title The Melville Boys implies that the two men in this four-character play are at the crux of its plot. For me, though, the highlight of the Richmond Hill Barn Theatre's production of Norm Foster's script was watching Dianna McKune provide the performance's heart and soul. As Mary, the character whose home neighbors the family cabin that the Melville brothers are using for the weekend, McKune brings a centered warmth to the proceedings, and is responsible for the play's biggest laughs and most heartfelt moments.

Given the actor's penchant for overacting - which suited her as Lina Lamont in Countryside Community Theatre's Singin' in the Rain two years ago, but which, for me, sometimes breaks the theatrical illusion - it's clear that either McKune's talents are improving, or that Melville director Eugenia Giebel inspired one of McKune's best performances to date.

During these moments, McKune can be seen in the background disapprovingly rolling her eyes, scowling, or eying another character. Yet despite the over-dramatic nature of these facial expressions, McKune employs them with sincerity. She's constantly in the moment here, with thoughts registering in her eyes and expressions every minute she's on stage.

McKune's tear-filled reaction approaches being over-the-top, but thankfully never reaches it, effectively eliciting laughter as her Mary scolds Lee for slipping the phrase "I'm dying" into their conversation without warning. She's comical without being clownish in her crying. And moments later, as the tension settles, McKune's tears - accompanied by her almost whispered vocal deliveries - led to what was, for me, the tenderest moment in Friday's production.

Up to this point in the plot, The Melville Boys' conflicts have to do with whether Lee and Mary will hook up, given that each of them is already married, and with Lee's younger brother (Victor Angelo's happy-
