Name the cast of A Gentleman’s Guide to [name_u]Love[/name_u] and Murder based upon the style and connotation of the names of the original Broadway cast, which you can find here!
Note: The given names listed are based upon the stage names of the actors, and thus do not include middle names unless the stage names do; they also include nicknames because, for instance, [name_m]Josh[/name_m] Groban presents himself so rather than as [name_m]Joshua[/name_m] Groban. [name_m]Feel[/name_m] free to lengthen nicknames and/or use the lists to give both first and middle names.
