The Theater at Monmouth began its 47th season with a classic tale scaled down to its romantic essence and generously flavored with comedy. Jo Roets’ adaptation of Edmond Rostand’s 1897 work “Cyrano de Bergerac” employs just three performers and takes only 60 minutes to sketch the story of an extraordinary 17th-century poet/hero whose insecurity about his physical appearance forces him to put his words of love into the mouth of another man. Christopher Holt takes the lead role, sporting a noticeable but not-all-that-big prosthetic nose that is the object of many jokes.
