Act 1 DeSales University Theatres delightful production of "The Importance of Being Earnest" crackles with wit and humor on the Main Stage of the Labuda Center for the Performing Arts in Center Valley through March 5.The actors pitch-perfect performances elevate Oscar Wildes 1895 comedy which sizzles with crisp wordplay and outrageous situations. Wildes satire of Victorian conventions relies on his rapid-fire dialogue, and the performers in this production delivers those words with precision and obvious glee. The comic timing is impeccable.
