Judy Blazer starred on Broadway in Me and My Girl (Sally), A Change in the Heir (Prince Conrad), Titanic (Lady Caroline), Neil Simon’s 45 Seconds from Broadway (Cindy) and played Brecht’s mistress in LoveMusik, directed by Harold Prince. Gentleman’s Guide, according to press notes, "tells the uproarious story of Monty Navarro, a distant heir to a family fortune who sets out to jump the line of succession, by any means necessary. All the while, he’s got to juggle his mistress (she’s after more than just love), his fiancée (she’s his cousin but who’s keeping track?), and the constant threat of landing behind bars! Of course, it will all be worth it if he can slay his way to his inheritance… and be done in time for tea."

The Tony-winning musical features a book by Robert L. Freedman, music by Steven Lutvak, and lyrics by Robert L. Freedman and Steven Lutvak. Darko Tresnjak directs, and Peggy Hickey choreographs.
