It was mentioned – more than once – at its opening-night performance that the Circa '21 Dinner Playhouse’s production of Diamonds & Divas: A Murderous Fiasco was the comedy's United States professional premiere. If we were supposed to be impressed by that fact, it really isn't saying much, as author Robin Hawdon's script would feel right at home with a group of American middle-schoolers. However, the cast, composed of many familiar Circa '21 favorites, injects talent amidst the chaos of this melodramatic escapade, almost fully redeeming an otherwise ridiculous affair.
