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.
