I'll say it again: John Legend as Pierre, Nicole Scherzinger as Helene, Adam Lambert as Anatole. That would be fantastic, and a triple-play like that would be a dream. Realistically, even one of those would be big. Nicole would draw at least Ingrid-sized crowns, while Adam and John could be Groban-level draws.
