The Importance of Being Earnest, according to Paper Mill, "is about maintaining fictitious identities to avoid unwelcome social obligations. Jack Worthing's brother, Earnest, provides Jack with the excuse to escape from his dull home in the country to frolic in town. The home of Algernon Moncreiff's friend Bunbury provides a convenient locale for taking adventures in the country. The problem? Earnest and Bunbury are imaginary, created by Jack and Algernon to add a dash of excitement to their lives. Their deceptions eventually cross paths, resulting in a series of hilarious crises that threaten to spoil their romantic pursuits."
The production features scenic design by Alexander Dodge, costume design by David Murin, lighting design by Matt Frey, sound design by Randy Hansen and hair and wig design by Mark Adam Rampmeyer. The production stage manager is Charles M. Turner, III.
